AFAIK REMOTE_ADDR (as most other $_SERVER variables) is coming from the webserver itself: http://lxr.php.net/xref/PHP_5_5/sapi/apache/mod_php5.c#254 http://lxr.php.net/search?q=REMOTE_ADDR&defs=&refs=&path=&hist=&project=PHP_5_5 I suppose it will contain whatever address your server received the request (be that an ipv4 or ipv6 address). on the other hand gethostbyname by definition returns an IPV4 address for the given host. this is the intended and documented behavior. there is an open feature request (with a patch) for changing that behavior to return IPv6 address: https://bugs.php.net/bug.php?id=49493&edit=1
personally I think that we should introduce this feature without breaking any BC, so a new function or a new optional argument should be added. -- Ferenc Kovács @Tyr43l - http://tyrael.hu
