What can be done to get a web site that appears to refuse to resove under IPv4 to work?
ipv6 is disabled and isn't going to be enabled for this.
I've heard rumours that in some parts of universe IPv4 is actually not available anymore. In such case it's only logical to have some host name only resolvable to IPv6 address. Perhaps time has come to implement 6to4 gateways ... to allow IPv4 only clients to connect to IPv6 servers ...Maybe the owner is fan of IPv6 who was annoyed by slow adoption and decided to give it a little push by cutting off IPv4?
