Hi!
I just noticed that the php function gethostbyaddr is not able to lookup
IPv6 mapped IPv4 or native IPv6 addresses.
Because I get such addresses from the apache 1.3.19 when it is patched
with the KAME IPv6 patch (that's the normal way to IPv6 enable apache
1.3) I noticed the problem.
Attached is a patch that enables php to lookup such addresses too.
Tot kijk
