Wrong IP Address outputted ?

[jjmpsp]

For some reason, when I output my ip address in PHP, I get this result:

echo $_SERVER['REMOTE_ADDR'];

::1

I'm running an XAMPP installation on a new windows 7 64bit machine.
Does anyone know what is happening ? This is really bugging me and I can't seem to find a solution

That is the IPv6 version of 127.0.0.1 or localhost. So it is your IP if you are running the server on a local machine.
