That's 0:0:0:0:0:0:xxxx:yyyy or ::xxxx:yyyy isn't it?
Is this something I need to worry about also?
Possibly. These are RFC2893 addresses. I'm not sure how widespread they
are -- I think it's mostly obsoleted by 6to4 (RFC3056).
Completely. They're officially obsolete. (I can't remember which RFC did
it, though)
I think if you fall back to the IPv4 records for 2002::/16 you should
probably fall back to the IPv4 for ::xxxx:yyyy too. Remember not to do
::1 though :)
Oooh, don't fall back to IPv4 for 2002::/16. They're different,
completely.
