Re: c-ares + IPv6 problem

Ah, I didn't notice those, thanks. I'll change it.

Also I think the IPv6 one might be wrong, according to this page (and
other people's comments):

The longest IPv6 address is actually something like:

1111:2222:3333:4444:5555:6666:123.123.123.123%1234567890 (57 chars long)
