you mean REMOTE_ADDR? what SAPI are you using?
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=3DREMOTE_ADDR&defs=3D&refs=3D&path=3D&hist=3D&p=
roject=3DPHP_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=3D49493&edit=3D1

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.
