Description:
------------
Hello,

I have a system e.g.:
hostname: localhost
ip1: ::1
ip2: 127.0.0.1

(the problem is not specific to localhost)

A fopen('http://localhost/', 'rb');
connect correctly to "::1".

But gethostbyname('localhost'); returns "127.0.0.1".
gethostbynamel('localhost'); also returns only a array with
"127.0.0.1".

Well, how can I know which IP PHP is using in a e.g. fopen() call?

And if gethostbyname() can't work with IPv6, this should be noted in
the PHP manual. From what I can see, gethostbyaddr() is also working
only with IPv4 (don't see this in the manual).

In phpinfo() i can read:
| IPv6 Support 	enabled 

Regards,
Carsten
