Here is a patch (applies to 5.3.1 ext/standard/dns.c)
If ipv6 is enabled, it will try first and fallback to ipv4 resolution
if no record is found.

Description:
------------
The php function gethostbyname currently only returns IPv4 addresses as
stated here:
http://us2.php.net/manual/en/function.gethostbyname.php
My feature request is, it should be able to return IPv6 addresses too.
