That's because they are among the few that apparently have IPv6 enabled web systems.They don't have "IPv6 enabled web systems", a lot of people wished that they did. What your problem most likely was, was a broken DNS server, which, when queried for an AAAA simply doesn't respond.In fact, it's one particular vendor (whose name I haven't been able to discover) of pay-for-Internet transparent proxy/NAT devices, such as those commonly used in hotels and at hotspots, that's messing the whole thing up. They return an address of 0.0.0.1 in response to any DNS query from an IPv6-capable client, and they've decided to train their service providers' tech support departments to tell customers to turn off v6 rather than fix what should be a very simple bug.
the STSN devices? or 'ibahn' ? One thing to keep in mind is that the DNS-LB used by Google/yahoo (in the examples above) seems to be returning a CNAME for AAAA queries, then nothing for the follow-up resolution request for a AAAA for the CNAME... So, ipv6 things may look 'broken' because they are also 'slow' (waiting to re-do much of the lookup path to get the A version)
