IPv6 Glue Why registrars need to support it Elise Gerich VP, IANA
State the problem IPv4 will be fully allocated very soon 2
3 Things change next quarter Over 320m IPv4 addresses have been allocated so far in 2010. There are only 115m addresses remaining. They will have been allocated by mid-2011
4 State of the IPv4 Pool About 4% of total IPv4 space is left in the pool. That is approximately 180m addresses. Photo by Silverstealth
5 Why should I care? IPv4 only has enough addresses for half the world’s population of 7 billion For the Internet to continue to grow it will need IPv6 If registrars don’t support IPv6 glue, their customers won’t be reachable by the entrants
What is DNS glue? Important for networks that run their own DNS 6
7 What is glue? Why is it needed? DNS glue is a normal part of DNS. All registrars currently support IPv4 glue registration Adding IPv6 glue support is a simple change to your web interface and registration database
8 What is glue? Why is it needed? I can ask the TLD’s nameservers where the web site I want to visit is

Let’s recap I need to get this sorted by the start of Q2 2011 because… 13
IPv6 glue or customers will go! The last five IPv4 blocks will be allocated by mid-2011 Internet growth will need IPv6 Domain registrants will to sell to people using IPv6 So they will demand IPv6 glue They’ll transfer if you don’t offer it 14 Photo by Revisorweb
