I found an old patch that makes analog only support ipv6 addresses: http://yasu.asuka.net/soft/patch/analog-5.03-ipv6.patch.gz
Based on that, here's a patch that makes analog support ipv6 in addition
to ipv4, by first trying to parse the address as ipv4, and falling back
to ipv6 if it's not an ipv4 address.
