Maybe there is a routing problem on > your or your ISP's side? Nope. I can get to IPv6-only sites just fine. And my E-Mail and DNS over IPv6 is fine. So, I'm able to get to IPv6 sites and they're able to get to me. It's just sites with both an "A" and a quad A "AAAA" record for the same name. Seems like a fairly recent update. Are you fully up to date with the latest yum updates? I'm going to check further with my upstream (OCCAID) and make sure there's no other peculiarities but this doesn't behave like other problems I've seen. Oh... And one other thing... Even internally, where my servers have both an IPv6 and IPv4 address, it use to be that doing an ssh to them would result in a connection to the IPv6 address. Now it connects to the IPv4 address. But, if I use the IPv6-only name, it does connect to IPv6 just fine. So there's no routing problems or firewall problems in that case. > Regards, > Andreas. Mike -- Michael H.
