Answer 1

Technically, you are getting the right IP. ::1 is your loopback (localhost) IPv6 address.

Answer 2

First, throw this stupid function away, because HTTP_X_FORWARDED_FOR is not an IP address but merely an HTTP header, and make it just

$Users_IP_address = $_SERVER['REMOTE_ADDR'];

Next, you have to set up your server to work with ipv4, not ipv6.
Though it is not really a PHP question and should be asked on the serverfault, provided with full system setup: OS, version, your rights etc.
