Re: IPv4 flag day

[David Prall via NANOG <nanog () lists nanog org>]

US Federal Government was supposed to be Dual-Stacked years ago and in 
fact should be running IPv6-Only already and already planned for 
replacement of anything they couldn't convert to IPv6-Only.

So if you get brought before congress you can ask them why they had 
issues getting to your IPv6-Only service from their IPv6-Only network.

It might have been caused by Cogent and Hurricane Electric, without 
finger pointing.
