IPv6 uptake (was: The Reg does 240/4)

[Stephen Satchell <list () satchell net>]

Several people in NANOG have opined that there are a number of mail 
servers on the Internet operating with IPv6 addresses.  OK.  I have a 
mail server, which has been on the Internet for decades.  On IPv4.

For the last four years, every attempt to get a PTR record in ip6.arpa 
from my ISP has been rejected, usually with a nasty dismissive.

Today, I'm trying again to get that all-important PTR record.  If I'm 
successful, then I expect to have my mail server fully up and running in 
the IPv6 space within 72 hours, or when the DNS changes propagate, 
whichever is longer.
