There really is no winner or right way on this thread. In IPv4 as a security guy we have often implemented NAT as an extra layer of obfuscation. It's worse than just obfuscation. The 'security' side effect of NAT can typically be implemented by four or five rules in a traditional firewall.

The last mile for the Level3 is coming on Telus (after a punch to the face and gut for build out fee) so I'd like someone else. Shaw does not offer service without what I suspect is another punch to the face for a build out. Bell didn't return any of my inquiries via email of voice message.

Sorry, poorly worded. What I was wondering is there is an equivalent of KA9Q for IPv6. I believe one of the comments we got back when we were trying to reclaim 44/8 was that folks couldn't migrate to IPv6 because no software was available... We've come a little way since NOS. Linux has

because most of the end users who would be querying it are in Canada, and, with one nameserver in Canada and one in Japan, they would get a long RTT on DNS queries roughly half the time. But only, say, once per week if you're running a reasonable TTL on your zone.
