Who is your ISP? Quite often these days you'll get a free static IP  
added to your account either as part of your package or if you ask  
nicely.

If you can't get a static IP, I've used DynDNS.com in the past  
sucessfully and a number of routers now come with the ability to  
perform DynDNS updates.

HTH,
