should $ip=$_SERVER['REMOTE_ADDR']; return ::1 on a mamp localhost?

I am trying to get the IP address of the website visitor in PHP. I'm expecting $_SERVER['REMOTE_HOST'] to return something like 127.0.0.1, but it's returning ::1.

Your server is misconfigured. is it shared hosting or some dedicated server? — Your Common Sense, Mar 20 '10 at 05:39
Well somehow it returns ipv6 address instead of ipv4 one. You can either try to reconfigure it or just leave it alone. — Your Common Sense, Mar 20 '10 at 05:53

::1 is the IPv6 equivalent of 127.0.0.1 - see http://www.juniper.net/techpubs/software/erx/erx50x/swconfig-routing-vol1/html/ipv6-config5.html The long form of that is
0:0:0:0:0:0:0:1 - but the :: stands in for the run of 0's.

The variable you're looking for is:

<?php echo $_SERVER['REMOTE_ADDR']; ?>

Could it possibly be an IPv6 address? – Peter Mar 20 '10 at 05:30

There are two possibilities here:

the address is ipv6. this has already been pointed out so i think this isn't the case
there is a firewall running on the server. as you say this is your local web server, check for any firewalls on it as some firewalls do block the server information.

Let know how it goes.

PHP $_SERVER['REMOTE_HOST'] returns ::1
