4. The Internet has Run Out!
At 14:30 GMT on Thursday, 3rd February 2011, a ceremony and press conference was held where the five remaining sets of 16.7 million addresses were handed out to the five Regional Internet Registries (RIRs). Rod Beckstrom, ICANN chief executive, said “This is one of the most important dates in internet history ... the pool of four billion [IPv4] internet addresses has been emptied this morning — there are no more.”
Our RIR is RIPE, who received one of the sets. Oxford University isn’t likely to see any of this new space as we had already been given about 132,000 IPv4 addresses. However, we only have a few percent of that left. Like the rest of the world, Oxford University will soon need to embrace IPv6.
For most of you, not a lot. Everything should just keep on working as it does. You won’t often see an IP address but if you do, IPv4 addresses look like this 188.8.131.52 and IPv6 ones like 2001:630:440::1. For OUCS and IT staff, it means a bit more effort. Have a look at our web pages to find out more.
On the 8th June many major organisations including Google, Facebook and Yahoo will be making their primary website online using IPv6. Many organisations already have their websites accessible via IPv6. They often use a different name e.g. ipv6.google.com or http://www.v6.facebook.com. On the 8th of June all participating websites will be directly IPv6 accessible ('resolved' in the jargon) using dual stack technology and provide a AAAA record for the site. IPv4 websites will of course continue to be accessible over IPv4 during the event.
As part of that day we’d like to have web servers run in the University of Oxford to be accessible using an IPv6 address, as well as their usual IPv4 address. We’ve already got a number of volunteers but more are welcome. If you’d like to take part contact Guy Edwards (firstname.lastname@example.org) who will be pleased to give you advice.
