IP Address of the machine in PHP gives ::1 but why?

Question

I am trying to fetch the ip address of my machine through php. For that I am writing the code like:

<?php echo  "<br />".$_SERVER['REMOTE_ADDR'];?>

But this piece of code is not working. It is returning "::1". Please help me how to get the actual IP Address.

Answer 1

::1 is the actual IP. It is an ipv6 loopback address (i.e. localhost). If you were using ipv4 it would be 127.0.0.1.

If you want to get a different IP address, then you'll need to connect to the server through a different network interface.
