You know, I need to update that page. If anyone has ideas for things for me to add email me.

Since this post has been answered, I can say there is one more thing you can do with an ip address:

IP Spotting - How interesting is your IP?

But yea, IP's are easy to obtain, learning how ip addresses work and how ports work is important.

So an application creates a socket, and binds that socket to a port, it then uses this socket enabled port to send and recieve data. The data is formed into packets, the headder of the packet contains your IP. This is required so the comunication can happen, otherwise the system you are trying to talk to wont know who to send the responce to.
