Apparently the need for IPv6 isn't yet high enough to consider adding
a
transit provider. I've seen enough press releases from NTT and HE to know there's at least two that can do this out there.
I believe the major holdup at this point is lack of v6 eyeballs. End user CPE, particularly DSL CPE, has been lagging in v6 capability. As for v6 upstreams, I have native v6 with both InterNAP (may not be available at ALL POPs yet) and HE. Savvis has yet to deploy it in the US at the POP pertinent to our operatons. The big push for v6 eyeballs at the current time are the mobile operators. We are seeing activity that would indicate there are mobile devices out there that are native v6 at this time. Content providers who have a lot of mobile clients might find they have more native v6 eyeballs than they think they have. A couple of things you can do to check. First of all look for requests to your DNS servers for AAAA records and note where those are coming from. That doesn't prove a lot but it gives some indication of who might have v6 someplace in their network. If you are seeing a significant number of these, the next thing I would do is get a dns server on your network working with v6 and get that IP address in whois even if all you are serving is v4 A records. Then note who is arriving over v6 asking for AAAA records. Those are the best candidates for enabling v6 services. Note which services those are asking for, pick one, and if you have gear capable of it (say, for example, a load balancer), configure a v6 VIP for that service balancing to v4 servers behind it. Place the AAAA record for this service in the zone handed out via v6 AAAA requests (ONLY!) and watch the service VIP and see if clients are connecting. So at this point you are handing out AAAA records for a v6 service but ONLY for DNS requests that arrive via IPv6 asking for it. Any requests arriving via v4 asking for an AAAA record would get the NOERROR response and an A record for the resource (client might have IPv6 internally but doesn't have v6 all the way to the Internet or their Internet coverage might be "spotty" and doesn't include you coughCogentcough).
