Hi, I'm Iljitsch van Beijnum. These are all posts about IPv6.
Your current connection to the web server is over IPv4, using address 3.16.51.237.
Checking your IPv6 address (this requires javascript)...
This document specifies how the level 3 multihoming Shim6 protocol
(Shim6) detects failures between two communicating nodes. It also
specifies an exploration protocol for switching to another pair of
interfaces and/or addresses between the same nodes if a failure
occurs and an operational pair can be found.

As of January first, 2009, the number of unused IPv4 addresses is 925.58 million. On January 1, 2008, it was 1122.85 million. So in 2008, 197.27 million addresses were used up. With 3706.65 million usable addresses, this means that 75.3% of the available IPv4 addresses are in some kind of use, up from 69.7% a year ago. So the depletion of the IPv4 address reserves is continuing in much the same way as in previous years.

When I was a research assistant at UC3M / IMDEA Networks in Madrid, I had occasion to visit the University of Cambridge for a week. Apparently, they have a rule that everyone who visits must do a presentation about their work. So I talked about the Shim6 protocol that I had been working on previously in the IETF. These are the slides; University of Cambridge Computer Lab, 2008-10-1.

For some time, I've maintained a number of pages that show address and AS number statistics generated from the delegation reports published by the five regional internet registries on their FTP servers. Time to make a list.

On February 4, 2008, ICANN will add IPv6 addresses for four root DNS servers to the root zone file, making full IPv6 Internet connections a reality. Time to check that DNS software and those firewalls to avoid any possible trouble.

In 2007, the number of available IPv4 addresses went down from 1300.65 million to 1122.85 million, a difference of 177.8 million addresses. The number of usable addresses is 3706.65 million, so on January 1, 2007 we were at 64.9% utilization and a year later we're at 69.7%.
