The better fix looking at the patch you proposed would
be to use the
function that detects is valid ipv6, not just something starting with
'['.
this has nothing to with what is valid ipv6, but rather, how does a
valid domain name look like. domain name consists of labels separated
by dots and my understanding is that each label consists of letters,
decimal digits and - chars. it makes sense to make a dns query only on
such a valid domain name.
an ipv6 address can thus never be a valid domain name. an ipv4 address,
on the other hand, is syntactically valid domain name and perhaps
someone has populated their local name server with such names.
