I doesn't look like a static IP address and a domain name (like .com) are the same. I just got a renewal notice from InterNIC and the only IP it mentions is my ISP's one. I sent a ping to my domain name. It gave me IP that looked like ISP's one, except the last two digits. I tried to use this IP with the browser and got bounced by the ISP's server, but I could reach my web site by using my domain name. Then I used "ping -a" option and it gave me ISP's name, not mine. OK, first about IP addresses. These are broken up into four sections, the first three usually indicate a particular 'subnet' and the last segment a specific machine. Its highly likely that your ISP has many machines in operation, so the difference in the last two digits is not surprising. Domain names are simply a mapping to a specific IP address. However, since your ISP is probably hosting many web sites off the same machine (ie IP address), there must be something set up on the web server to read the domain requested and map that to the directories where your content is stored. When you just gave it a raw address, it could get to the right machine but didn't know where to go from there so it returned an error message (this is what you meant by 'bounced'??) If you had one machine dedicated to support your web site, then there would be a one-to-one correspondence between domain name and IP address.
