Post current IP address to .php
Okay, this is probably something not often done, but I am trying to write a simple script in order to _post my computers current ip address (rather the ip address of the network on the router) to a php script on a stable site. I do not have a static ip, I cannot acquire one, and having a dynamic ip may have its advantages. So firstly is there any function, I am in debian to note, that will give me the address I need, and is there any method or function to post something as I described. Thanks.
