HP Blogs – 6 steps for SMBs to become IPv6-ready – The HP Blog Hub

My Comments

There is all the talk of us running out of IPv4 public IP addresses for the Internet, and an increased awareness of IPv6 Internet technology. One major driver for the IPv6 technology is the rolling out of next-generation broadband services; where this feature will be seen as being part of the “next generation” mould.

In the near time, the typical IPv6 network will operate as a “dual-stack” setup where there is an IPv6 network and an IPv4 network operating over the same network space. A device such as an IPv6-ready router will typically bridge the gap between the dual-stack devices and the IPv4-only devices by assisting in the discovery of the devices and transferring data between the two different network stacks.

Outside IT contractors

If you do regularly engage outside contractors for your IT needs such as your POS / property-management technology, it would pay to ask whether the technical staff know about IPv6 and how to deploy it. Most of these contractors may think that small business doesn’t need IPv6 but as the Internet moves to this technology, it pays to be future-proof.

ISPs and Webhosts

It is worth making sure that your business’s ISP and Internet hosted services such as your Webhost are ready for IPv6 or have intentions to roll out a customer-facing IPv6 service.

Most ISPs and Webhosts are likely to have the backend of their services working on IPv6 technology but their customer-facing services like the Web services or Internet service may not be ready. This may be due to the presumption that most customer setups will fail when confronted with IPv6. The exception may be the ISPs that serve a “switched-on” audience that knows their way around the Internet technology; or ISPs and Webhosts that offer customer-facing IPv6 service as a limited-user beta test and they may offer a “dual-stack” setup.

It also pays to check that your domain host supports domain records that are compatible with IPv6 setups. This includes having AAAAA-form DNS records that can resolve your domain name to IPv6 addresses.

Hardware

Computers that run Windows Vista or 7, MacOS X Lion or recent Linux distributions will be ready for IPv6; with Windows XP having support through a downloadable module from Microsoft’s Web site. Relatively-recent computer equipment can be upgraded from prior operating systems to the newer IPv6-compliant operating systems. For the mobile platforms, the IOS (iPhone / iPad / iPod Touch), Android, Symbian and Windows Phone 7 platforms do support IPv6. They will typically operate on a “dual-stack” arrangement by being able to service an IPv4 network and an IPv6 network at the same time through the same network interface,

Similarly, most network printers pitched at the business end of the market that were released over the last few years would have support for IPv6 in a dual-stack setup.

As for routers, managed switches, access points and other network hardware, I would suggest that you check for firmware that supports IPv6 for your existing equipment. Keep an eye on the manufacturer’s Website for newer firmware updates that support IPv6.  If you are purchasing or specifying newer network equipment, make sure that it does support IPv6 or has future support for this in a planned firmware update. Most unmanaged switches, HomePlug-Ethernet bridges and devices that don’t use a Web or SMNP user interface would not need to be compliant with IPv6. This is because these devices work at levels below the IP stacks.

In the case of routers, the device should work as a “dual-stack” unit with support for routing between the two different IP network types. It should also be able to cope with working with a dual-stack Internet service especially as the business Internet services that provide IPv6 will do so in a dual-stack manner.

When I review any network hardware including printers, I will identify those pieces of equipment that are IPv6-ready so as to help you know whether the equipment will be future-proof.

Software

As for software on these computers, any desktop firewall software or other network-utility software that you run would need to support IPv6 operation. This is something that recent versions of this software would cater for, but you should make sure of this when you specify new software. It also holds true for any other network-management programs that need to work on an IP level.

The application software that serves office functionality or line-of-business needs wouldn’t be of concern in relation to IPv6 because the operating system would be handling the network-resource requests for these programs.

Conclusion

The key issue with assuring IPv6 compatibility for your small business network is to make sure that your computer equipment works on dual-stack IPv4/IPv6 software and / or there is a router that works as n IPv4/IPv6 bridge on both sides of the network-Internet “edge”. As well, the IT contractors and services that you engage would need to be knowledgeable about IPv6 and the impending rollout for your business.

Comcast shifts some customers to IPv6, promises it won’t hurt — Engadget

From the horse’s mouth

Comcast IPv6 Information Center

My comments

Comcast are rolling out a pilot deployment of IPv6-based Internet service. Here the customers will be those using a computer that is connected directly to a compatible DOCSIS 3.0 cable modem.

The computer will have to run Windows Vista or 7 for the Windows platform or MacOS X Lion for the Macintosh platform. This is because these operating systems are known to support a dual-stacked IPv4/IPv6 setup which the service will be based on. As well, these services will be provided with a unique full IPv6 address. Of course, Comcast will have 6to4 IP gateways in the network to bridge the IPv6 and IPv4 networks.

At the moment, there will be the rough edges through the deployment of this trial setup while the bugs are ironed out. A subsequent trial in the near future will then look at the use of home networks, but I would like to have this trial examine networks that are comprised of IPv4-only devices as well as dual-stack IPv4/IPv6 devices. This would also encompass access to legacy and IPv6 Internet services from both the legacy and the IPv6 devices.

Most likely this rollout will appeal and be targeted to some of the computer “geeks” who want to dabble in the latest setups. But I see it as a chance for Comcast, a mass-market cable-Internet provider, to put IPv6 through its paces before the full deployment commences. It also is an open chance for Comcast to put their findings about how their IPv6 deployment went to other cable-Internet providers who will be facing a requirement to roll up to this technology.

After all of the PR that has occurred around IPv6, which I have discussed previously on this site, there will be consumer and small-business demand for computer and network hardware and software that supports IPv6. This will be made more real when people subscribe to fibre-based next-generation broadband Internet or sign up with ISPs that offer any form of “cutting-edge” Internet service.

What will typically need to happen for most small networks is for the network equipment, especially the router that sits at the edge of the network, to support IPv6 in a dual-stack form. This may be achieved through a firmware update for most recently-issued existing equipment or will be part of recently-sold equipment.

Of course, a router manufacturer may say that their equipment is ready for the new standard but is it really ready when the ISP enables this technology? This includes interoperability with other IPv6 and IPv4 network equipment, whether the equipment works on one of the standards or is “dual-stacked” to work on both standards.

The IPv6 Forum (http://www.ipv6forum.org/) have established a logo program with a Website called “IPv6 Ready” (http://www.ipv6ready.org/). What you will be looking for is a yellow logo with “IPv6” on the router’s box. You can also check your device’s readiness on the IPv6 Ready website. At the moment, the logo list mostly points to OEM devices or software stacks rather than finished devices under their marketing names. But this logo will typically be found in the marketing literature for the device or on the device itself or its packaging.

This logo proves that the device conforms to IPv6 standards as a network hub or endpoint and works properly with other IPv6 and IPv4 devices on the Internet. This is facilitated by the device or software having to successfully complete a round of compatibility and interoperability tests in accredited testing laboratories before being authorised to display the logo.

There is also an IPv6-enabled logo for Web pages and ISPs that provide IPv6 access with the program at this site (http://www.ipv6forum.org/ipv6_enabled/). The Web-page program is underway and open to Webmasters who want to be sure their Website is future proof. It covers resolving of the URL to an IPv6 address as well as all-the-way IPv6 http access to that site.

The problem with all these logo programs is that there isn’t the customer-facing education that encourages customers to prefer equipment or services that are future-proof with IPv6. The services program could be augmented through promotion of IP services that are ready to provide IPv6 as a standard-issue service than something that you ask for. This also includes the service being enabled by default if a customer connects a dual-stack router to the service.

As the “World IPv6 Day” and similar campaigns gain traction, it will become the time for consumers and small-business owners to consider the benefits of the new IPv6 technology and what it offers.

Dossier -Test du Freebox Server | DegroupNews

Freebox Revolution – Test du Freebox Player | DegroupNews

From the horse’s mouth

Freebox Home Page – Free (France – French language)

My comments

Typically, the kind of equipment supplied to consumers by telecommunications carriers and Internet service providers for “triple-play”or similar Internet services has typically been drab in design and functionality. This is typically to work to the lowest-common denominator with both price, functionality and style.

The situation is very different in France where there is a lively competitive market for “triple-play”Internet service. Most urban or regional centres in this country are “dégroupée” for multiple competing ADSL-service operators. Here, these operators have access to the customers’ telephone lines as cable without paying France Télécom for a dial-tone service. There is also a steady rollout of fibre-optic service by the competing service providers for next-generation broadband Internet, with an overlaying requirement to provide competitive access to the ducts and poles for the fibre-optic service.

One of these major players is Free who have established a triple-play service for many years. Their latest iteration of the “Freebox” is now a benchmark for anyone offering a similar setup, whether in France or anywhere else.

I have previously covered the Freebox Révolution  in HomeNetworking01.info when a recent firmware update was released that integrated it with Apple’s ecosystem. As well, I have researched many French and English-language resources to learn more about this system.

The Freebox Révolution system

This system, like other triple-play setups offered in France, comprises of an Internet-gateway device, known as a “box”, and a set-top-box, known as a “décodeur”. These units have typically been interlinked by an Ethernet cable or user-supplied HomePlug kit, but is connected through a pair of “Freeplugs” which combine a power supply and a HomePlug-AV-Ethernet bridge in one box.

The units are a statement of industrial design in a similar way that Bang & Olufsen equipment are still a statement in this regard for consumer audio-video equipment. Both the Internet-gateway device and the set-top box have been designed by Phillippe Starck, known for extraordinary designs like the Parrot Zikmu network-enabled speakers or some of the LaCie external hard drives or network-attached storage systems.

Internet Gateway Device (Freebox Server)

This device consists of a broadband router, network-attached storage, VoIP ATA with DECT base station and audio player in one box.

It has a dual-WAN interface for either an ADSL2 service or an FTTH fibre-optic service. But the LAN functionality is one of the hallmarks of a cutting-edge device. It has 4 Gigabit Ethernet switched ports for Ethernet client devices as well as an access point for an 802,11n three-stream 450Mbps Wi-Fi segment. I mentioned previously that this unit also supports a HomePlug AV segment through the use of the supplied Freeplug adaptors. The Wi-Fi access point can also work as a separate “hotspot segment” for other Free subscribers.

The VoIP functionality works with an integrated analog-telephony adaptor and a DECT base station that you can associate 8 DECT cordless handsets with. These will provide full functionality with CAT-iQ DECT handsets.

The 250Gb NAS can work with the regular file-protocol suspects (CIFS, FTP, HTTP) but can work as a DLNA media server. It also works as a “staging post” for FTP, HTTP and BitTorrent downloads, the latter function being described as a “seedbox”. The recent firmware upgrades also implemented Apple TimeMachine support for incremental MacOS data backups. Of course, there is USB connectivity for 2 devices as well as eSATA connectivity for an external hard disk.

There are integrated speakers for playing media held on the hard disk, the Internet or an Apple AirPlay network but you can use it as an elementary amplified-speakers setup by connecting a Discman or iPod to its AUDIO IN jack. Of course you can play the music through better powered speakers or an amplifier using the AUDIO OUT jack.

This router is totally UPnP to the hilt with UPnP Internet-Gateway-Device for hands-free setup with Skype, games, MSN Messenger and the like; as well as being a UPnP AV / DLNA media server. Free could do better by integrating something like TwonkyMedia which can allow content discovery on metadata other than the file-system tree.

Let’s not forget that the Freebox Server is IPv6-ready as expected for a future-proof device. This is being augmented by the fact that ADSL Free subscribers in zone dégroupée aras or FTTH Free subscribers can have an IPv6 connection now.

Set-Top Box (Freebox Player)

This unit has an integrated Blu-Ray player with Blu-Ray 3D support (after new firmware added) as well as a digital-TV / IPTV set-top box / PVR. It connects to the TV via an HDMI connector or a SCART cable, both offering that “single-pipe” connectivity between the Freebox and the TV. Of course, there are connectivity options for other audio-video setups like SPDIF optical; and you can connect USB peripherals like SD card readers to this unit for direct viewing.

It is controlled via a gyroscopic remote control but has a supplied game controller as an alternate input device. Of course, you can connect a USB keyboard and mouse to it as extra input devices or control it from your iPad using the Freebox Connect app.

One drawcard in my opinion is that it is a fully-fledged Internet terminal with access to an app store, namely the FreeStore app store. This allows you to download games and similar “lean-back” apps; as well as view the Web or check email from your couch. Just of late, this set-top box has had YouTube support baked in to its latest firmware update.

You can now use the Freebox Player and its associated sound system or television’s speaker to play material from your iTunes software or iOS device using AirPlay. This at the moment applies to audio content only.As well, you can discover and play content held on DLNA-compliant media servers on your network including the Freebox Server’s hard disk.

Plans and Pricing

You can equip that French home or apartment with this device for € 29.90 per month. This gives you inclusive unlimited telephone telephone calls to standard phone services in most countries (Europe, Francophone countries, US, Australia, NZ, etc); and mobiles in France.

The Internet service would be up to 28Mbps while you have access to most basic TV service. Pay €1.99/month extra for 185 additional TV channels while you can service another room with Free’s TV service for €4.99/month extra with a simple set-top box or another of this Freebox Player for €9.99/month extra.

Existing Free subscribers can upgrade for €199.99 less €30 for each year they have been with Free.

The prices are obtained from Free’s latest tariff charts available on their site and would appear to be ridiculously low for people who live in a country that doesn’t have a lively competitive broadband-Internet market.

Conclusion

What I see of the Freebox Révolution is a system of equipment for a home network that is all about an Internet service provider offering a future-proof attractive cutting-edge piece of equipment rather than offering second-rate equipment to their customers.

This is primarily driven by a country who is behind a really competitive Internet service market for consumers and that the competition is driven on value rather than the cheapest price possible.

What You Need To Know About IPv6 – PCWorld

My Comments

There has been a lot of talk about IPv6 as becoming the next major change for the Internet ecosystem.

This talk increased since late 2010 with the fact that the Internet is running out of globally-assignable IPv4 addresses, which are used to identify Internet services to other endpoints on the public Internet. There would then be the requirement to frequently reuse these addresses which can lead to a confused Internet setup.

It has also been augmented by the “World IPv6 Day” taking place on June 8 2011 where most of the popular sites had to run a dual IPv4/IPv6 setup to test whether IPv6 is ready for prime time. This test passed with flying colours for all of these sites and some of them still run with IPv6 compatibility in one form or another,

It is a technology that will be put on the map more so with the arrival of next-generation broadband setups, either as a way of opening up more IP addresses or as a statement to say the these services are all about “next generation Internet”,

What does IPv6 offer?

Greater number of IP addresses

There is a greater number of unique IP addresses available in the IPv6 Internet than there would be for the current-technology IPv4 Internet.

This requires the use of long address strings that may be hard to understand. For example, a typical IPv4 Internet address would be something like 211.234.5.1 whereas the IPv6 Internet address would be something like 2001:0530:ac12:2333:03aa:12f3:fe21:53f2 . This is why some shorthands have been introduced like the one mentioned in the next paragraph.

If an address had four zeros in it like 0000, the shorthand for this would be two colons as in fe80::ac12:2333:03aa:12f3:fe21:53f2 being equivalent to fe80:0000:ac12:2333:03aa:12f3:fe21:53f2 . It is worth noting that any IPv6 address that starts with fe80:: (fe80:0000: in longhand) is a stateless link-local address that would be “worked out” between network devices unless there is an IPv6 router that has a DHCPv6 server handing out the addresses.

Different network addressing setup

In the current IPv4 world, an ISP would allocate each customer’s network an outside IP address like 211.234.5.1 with a netmask of 255.255.255.0 . All devices within the network would be allocated a site-local IP address and it would be the job of the router to map through using Network Address Translation a “port number” to an inside device’s address. This has often caused problems for network setup whenever a device had to receive information from the Internet, an activity that is becoming more common with applications like Internet gaming and IP telephony.

An ISP can now issue a network prefix to a subscriber like this: 2001:0530:ac12:2333 and the DHCP server in an IPv6 router can allocate a unique “full” IPv6 address for each of the network devices. There isn’t even the need for netmasks anymore because a network can be singled out by the use of the IPv6 prefixes.

It will also therefore provide for proper direct access to each unique node on an IPv6 network.

Therefore, you will end up with more unique IP addresses for your home or small-business network than the whole of the current-generation IPv4 Internet.

Different take on network security

The fact that each network device in an IPv6 network can be globally accessible requires a rethink of the role that the network-Internet “edge” device provides.

The role of these devices in a small IPv6 network will typically be to work as a security firewall for the logical network that is behind it. It will also be asked to work as a bridge between the IPv4 network, the IPv6 network and Internet services that work purely with IPv4 and IPv6. It will be augmented with Improved designed-in security with IPSec secure-network support.

What is the reality with IPv6

Most of us may think that our small networks in our homes, shops and small offices won’t touch IPv6. But there is a strong likelihood that it will be part of next-generation broadband Internet sometime in the near future.

Compatibility setups

The dual-stack network

The fact is that some of the devices you use for the Internet may be infact ready to work with the IPv6 Internet. They will typically work with the IPv6 Internet in a “dual-stack” form where they can support IPv6 or IPv4 network traffic over the same interface. This means that each device will be known on the network via an IPv4 address and an IPv6 address. It also leads to the fact that the network will work as though it is two different networks – an IPv4 network and an iPv6 network with the same physical infrastructure.

If you establish a network with two or more dual-stack IPv4/IPv6 devices with the IPv6 function enabled, you will end up with a dual-stack network with each device being known by a stateless IPv6 address. This is even though the network has a router that can only support IPv4 network setups and hand out IPv4 IP addresses from its DHCP server.

Inter-protocol tunnelling

As well, most routers that support IPv6 will implement tunnel setups that interlink data between regular IPv4 host systems and IPv6 host systems both within and outside the network. These are typically in the form of ISATAP or 6to4 protocols which manage this process automatically. Here, the routers will set up VPN-like tunnels between IPv4 networks over the IPv6 networks to link the resources that are behind these networks.

Who’s ready and who isn’t

Standard computers, tablets and smartphones

The regular computer and the smartphone will be ready for IPv6. This has been achieved with inherent operating-system support in the newer versions of the popular desktop and smartphone operating systems.

For example, Windows has inherent support from Vista onwards and has a “kludged-in” support arrangement for Windows XP. Macintosh users will have IPv6 support from at least MacOS X Snow Leopard onwards.

The two popular smartphone platforms, iOS (iPhone) and Android have inherent support in their current versions. This is because some of the mobile carriers run IPv6 networks for their wireless-broadband services.

Network-enabled equipment

Most small-business printers that are released by the big names over the past two years are IPv6 ready.This doesn’t hold true for consumer network printers or most consumer network media hardware for that matter. It also holds true for network-capable consumer electronics like the Internet radios that I have reviewed.

A selection of high-end consumer and small-business routers do support IPv6 in some way; usually in a dual-stack method  and/or providing IPv6/IPv4 routing functionality according to one or more common algorithms like 6to4 or ISATAP. It is still worth checking with your router vendor whether there will be IPv6-capable firmware available for your existing equipment or equipment that you plan to buy.

What I will be doing at HomeNetworking01.info is that when I review network-enabled equipment and find that it has IPv6 capability, I will identify it as being IPv6-ready in its connectivity list. This will allow users to know that the equipment they plan to buy or specify can he ready to work in the IPv6 age.

Internet services

At the moment, nearly all residential and small-business Internet services aren’t running IPv6-compliant Internet services. They may run an IPv6 network as part of their backbone or own-office infrastructure bot won’t enable IPv6 with their customer-facing services or the network links that reach their customers.

This situation may change with ISPs that are part of a next-generation broadband service or who provide “geek-friendly” Internet service with the latest and the greatest technology. But I would suspect that most ISPs will provide a dual-stack Internet service when they get around to providing the customer-facing IPv6 service.

Access to and hosting the Web

If you do set up a Web page with a service provider, you may have a different IPv6-readiness issue. Most Web hosts will run IPv6 on their backbone networks and may run IPv6 as a beta-testing service which isn’t all that “polished”; but they won’t have fully-functional IPv6 for their customer-facing Web sites or the sites that they host. This is because, at the moment,  most systems and networks won’t cope properly with “dual-stack” (IPv4 / IPv6) Web-host setups because of the primary reliance on IPv4 infrastructure.

After “World IPv6 Day”, most of the big sites like Google and Facebook had found they could operate as a dual-stack arrangement without "keeling over” or having negative impact on the end-user experience. This is even though most traffic that visits these sites originates from IPv4 networks. Therefore some of the major sites are still running dual-stack or maintaining their test IPv6 site as a separate subdomain.

What will this lead to

It may lead to the ability for many devices to be globally addressed in a small network and this may be of importance if these devices are to be directly accessible from the Internet. This will be of importance with gaming and remote-access applications, and may encompass the ability to have networks addressable through a premises-unique easy-to-remember subdomain.

It could also allow for multi-premises setups to be easier to establish and maintain due to the fact that a logical network can be set up to cover the different locations. This is as long as they work on one service account. It may not hold true of portable devices that are typically serviced by different providers’ accounts.

It may yield some controversies concerning individuals’ privacy and security because of the ability to provide globally-unique addressability for each device. This is along with the arrival of cost-effective network-based monitoring setups that could track every individuals’ movements.

Conclusion

This article is informing you about what is to be expected out of the IPv6 technology that is being highly talked about through this year. It also may be of relevance as we move towards households and small businesses being served by next-generation broadband services such as the many fibre-optic networks.
