Web Server

The answer is yes.
You will need an IP address, a domain name, and a DNS record.
There are alot of sites where you can get the 2 last ones (Domain name, and DNS record), your ISP should also be able to help you out.

If you want the whole story, there are two answers. The technical answer is yes - you can easily host a Web site on a static IP provided by your ISP.

The second part is legal and political. Each ISP has a set of rule for use of their facilities, usually called the Terms of Use. It's kind of like software licensing - if you want to use the product, you agree to the conditions regardless of whether you really agree to the conditions.

It is VERY rare for an ISP to permit hosting a Web site on a non-commercial DSL or cable account and when they discover your site, they will probably disconnect your service altogether, generally without a requirement for prior notice. It's kind of a bummer to have the plug pulled just when you get everything running smoothly.

So....get a copy of the ISP Terms of Use and review it carefully before you put up the site. You'll probably discover it's a very distressing, 1-sided, legally abusive, morally obnoxious and commercially unpalatable document, but it's what you have to work with.
