Setting a server.

Since most of home users sit on the Internet with Dynamic IP, there is a problem to find them from the ?Out Side World?.
Come in the saviors in the form of DNS Services. You register yourself with a DNS Service (some are free for personal use). They provide you with a Static address (or you can buy a TLD i.e. iamabigguy.com) and a little program that transmits to their server your current dynamic IP, while they show to the World your static address..
You can find detailed instructions for setting up DNS service here:
