The simplest solution is to order yourself up a T-1 line; that will take care of it.
You can ask for a static IP, but chances are that they can't help you. Static IP is usually an extra cost service, and I usually see the choice with DSL and ISDN service.
If your aim is to reach your home box from somewhere else, what you can do is sign up for a dynamic DNS service like <a href=http://www.dyndns.org/>DynDNS</a>. By using DDNS, you find your computer by using a regular hostname, like damagebox.dyndns.org, for instance. That'll impress everybody except hard-core geeks, BTW.
The way DDNS works is by having a script or program on your computer that connects to the DDNS provider every once in a while. The script tells the DNS service what IP address your computer is using at the moment, and the service adapts instantly.
You are false data.
