[dns-operations] Resolver operation an expired domain

[Frank Bulk]

Sounds like a side-campaign that should be launched before World IPv6 Day.
Has anyone checked the DNS records of the publicly announced participants to
see if they suffer from this "." issue?

And verisign should know better.  While verisign gets this wrong
how can we expect everyone else to do the right thing?  2% of the
Alexa list get this wrong (includes verisign).  This is significantly
hampering IPv6 deployment as it slow up IPv6 resolution.
