Gah. I guess this is the cause of some of my weird hangs in Mozilla too.
Doing a quick google, it would seem that on FreeBSD, setting:
net.inet6.ip6.v6only to 0 /should/ resolve this problem (by checking the
ip4 IP first), but doesn't seem to fix it for me. I have no intention of
having an IPv6 connection on any of these machines any time soon, but it
seems a bit annoying to have to completely remove ipv6 support just to
"fix" this.

I guess putting "-4" in .digrc will do the trick.

A bit OT for this forum, but do I have any options on FreeBSD or OpenBSD
other than rebuilding the kernel / OS without ipv6 support?
