IPv4 and IPv6 addressing – part 4

Today, the standard methods for moving the network/host address boundary are variable-length subnet masking (VLSM) for host addressing and routing inside a routing domain, and classless interdomain routing (CIDR) for routing between routing domains. (Well talk more about routing domains later in this book. For now, think of a routing domain as an ISPs collection of routers.) And although treated separately here for introductory reasons, it is important to realize that VLSM is the fundamental mechanism of CIDR.

CIDR (defined in RFC 1519) and VLSM (defined in RFC 1860) address more general issues than simple subnetting. Weve been looking at addresses from the host perspective in this chapter so far. Lets discuss CIDR from the router perspective.

Conseil Régional de Basse-Normandie deploys IPv6-ready collaboration technologies to simplify IT infrastructure and increase operational efficiency

Cisco today announced that the Conseil Régional de Basse-Normandie (CRBN) has deployed Cisco Unified Communications Manager, running the new version of Internet Protocol (IPv6), to simplify its communications infrastructure. The deployments will facilitate the implementation of new IPv6-based collaboration applications and services and help improve operational efficiency. The new system will operate with the council’s VIKMAN research and education network, which uses the IPv6 protocol to provide a high-speed Internet connection between all of the region’s research and training sites. CRBN is one of the first councils to deploy the latest version of Cisco Unified Communications Manager, running IPv6.

T-Mobile is pushing IPv6. Hard.

T-Mobile USA has launched an IPv6 web site -- http://ipv6.t-mobile.com/. Only the front page (including images and CSS) is reachable over IPv6; most of the links are broken or redirect to the IPv4-only site. Clearly, it's still a work-in-progress. This appears to be a futher development in their IPv6 strategy announced at Google's IPv6 Implementors Conference few weeks ago. (Btw, the conference was quite good; hats off to Erik, Lorenzo, and the rest of the Google team.)

T-Mobile USA makes heavy use of NAT44 and bogon addresses. Going forward, this isn't sustainable. So they've decided that future cellular deployments will be IPv6-only, with NAT64 to access the "legacy" IPv4 Internet (slides | video). Yes, NAT is bad, but this approach is the least-bad of the alternatives. There's still only one layer of NAT, it gets IPv6 on a large number of end nodes, and IPv6-enabled content (Google, Netflix, Facebook, etc) isn't NAT'ed at all. Over time, less traffic should flow through the NAT64 boxes as more content is IPv6-enabled. T-Mobile USA suspects they can run 50% of their cellular data traffic over IPv6 by the end of 2011 (apparently they send a lot of traffic to Google and Facebook).

On a personal note, it was very entertaining to hear Cameron Byrne from T-Mobile USA repeatedly tell content providers, "Our users are going to access your content over IPv6. The only relevant question is 'will we make the AAAA record or will you?' Wouldn't you rather be the one to do it so you have control?" After the fourth or fifth time it sunk in: These folks are serious.

This is an even gutsier move than Verizon. VZ is dual-stacking their LTE network and mandating IPv6 support on all devices. Let's hope T-Mobile is really good at running large-scale NATs.

Last Call : 2010 Global IPv6 Deployment Monitoring Survey

This is a last-call reminder to participate in the 2010 Global IPv6 Deployment Monitoring Survey, conducted by GNKS Consult and TNO in collaboration with the RIPE NCC.

The survey is available at:

http://www.surveymonkey.com/s/IPv6deploymentmonitoring2010

The deadline to complete the survey is this Thursday, 1 July 2010.

All five Regional Internet Registries have committed to soliciting participation in this survey in order to compile the most complete global IPv6 deployment data possible. The goal of the survey is to gain a better understanding of where the community is moving, and what can be done to ensure the Internet community is ready for the widespread adoption of IPv6.

We encourage all organisations in the RIPE NCC service region to participate in this survey, which we hope will establish a comprehensive view of present IPv6 penetration and future plans for IPv6 deployment.
The survey is composed of 23 questions and can be completed in about 15 minutes. For those without IPv6 allocations or assignments, or who have not yet deployed IPv6, the questions will be fewer in number.

Results of the IPv6 Deployment Monitoring Survey will be presented and discussed at RIPE 61, which will be held 15-19 November in Rome, Italy.
Results will also be published on IPv6 Act Now:

http://ipv6actnow.org

Please provide your name and contact information on the survey form if you wish to receive the draft survey analysis when available. Please also indicate whether you are willing to share additional data with the TNO and GNKS Consult IPv6 Deployment Monitoring team.

Any questions concerning the survey itself should be addressed to <info@gnksconsult.com>.

Regards,

Paul Rendek
Head of External Relations and Communications RIPE NCC

ARIN’s Guide to IPv6 Preparedness

Every device directly connected to the Internet needs an IP address. There are two versions: IP version 4, better known as IPv4, and IP version 6, aka IPv6. IPv4, the current version, holds 4,294,967,296 addresses, and about 92 percent of them have already been distributed. IPv6, the newer version, holds 340,282,366,920,938,463,463,374,607,431,768,211,456 addresses.

The issue is simple: IPv4 addresses are running out, and fast. The solution to the address depletion is IPv6. This seemingly endless number of addresses holds the future of the Internet, but it requires companies that use and distribute IP addresses to adapt their networks and systems to use IPv6.
