IP-Address in Profile

First topic message reminder :

Hello. I have been working as Administrator for a forum and They have asked me they want in the Profile area and only Administrators to see it. I need the IP to appear automatically in the text box without me having to fill each text box of each member manually. I have already created the field I just need the IP to be added automatically. is there any CSS, Javascript or Html code to make this a possibility?

Strange!
Open this http://wtfismyip.com/json link and see the result returned in json

JS

It's been working. And not only that something I like is that the users that already existed also display their IP. So far this is working pretty good. About the IPv6 I have no idea why it happened but it seems to have stopped.

@JScript vpn OP 

True if I use an IP from Norway let's say it registers it rather than my real IP but still works great.  I think this might finally be solved maybe.
