I tried your second patch, but it didn't make a difference. I'll take
the easy way out for now and add a DNS entry like you and ume suggested.
:-) I looked in ifconfig to see how they did the anycast detection and
you basically have to open another socket into the kernel (this time
an AF_INET6 one) and get the ipv6 flags and check them. Maybe too much
work, except if it is going to bother too many people. :-/
