ARIN, the resource registry that hands out allocations for IPv4 addresses, has announced that it has no more IPv4 addresses to give out. Although this doesn't mean no more IPv4 addresses will be allocated, it has brought to an end the question of when such addresses will run out. Meanwhile, IPv6 usage continues to climb with the release of iOS 9.
Today is World IPv6 day, when large organisations will enable IPv6 resolution of their hosts will be enabled permanently. This follows on from last year's successful tests when IPv6 connectivity was enabled for a day.
Following on from the success of last year's World IPv6 day, in which major organisations such as Facebook and Google enabled IPv6 connectivity for a 24h period, the Internet Society has announced Google, Facebook, Yahoo and Bing) and on World IPv6 Launch Day (6th June 2012) the websites will switch on their IPv6 support and leave it permanently enabled.
World IPv6 Day proved to be a success. Major service providers and websites are ready for IPv6, but some experience response times lower than when using IPv4. Experts draw attention to a possible security flaw in IPv6 implementations.
June 8th 2011 is World IPv6 day, where many large internet organisations such as Google and YouTube, and social networks like Facebook have IPv6 enabled their sites for at least the next 24 hours. If you have an IPv6 connection, then when you visit these sites you'll be going over the IPv6 network instead of the IPv4 network.
The Internet Society has called for a World IPv6 Day on 8th June 2011 to promote the use of IPv6 by major organisations such as Google, Facebook and Akami. With IPv4 blocks expected to run out in the next week, the timing for the announcement could not be better.
The number of allocatable IPv4 addresses has dropped below 160 million, leading to predictions that the IPv4 address space will be used up in less than 100 days. What does this mean?
This week, the Number Resource Organisation, the official representative of the five Regional Internet Registries and who oversees the allocation of IP addresses, announced that less than 10 percent of IPv4 addresses remain unallocated. If it's not addressed in the near future, the ramifications could be serious for the world wide web.
