AAAA, and I'm not talking bonds or insurance.
The root name servers now officially have AAAA glue records installed. This is actually a pretty major step towards global IPv6 deployment. There was a few snafu/foul-ups, mostly regarding VeriSign not setting the connection limit high enough on ftp.rs.internic.net so causing a mirror failure.
What does this mean to you, as someone who’s on the internet? Not a damn thing probably since most ISPs and NSPs haven’t begun to widely deploy IPv6. That said, I’ve added AAAA records for dotblag.com here which is more or less IPv6 ready. What we lack is lots of good direct v6 transit because our neighbors haven’t yet gotten it deployed. It’s on the list of things to push against them on.
