<< 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.>> This is essentially correct, but these days addresses are divided on a finer grained boundary than on the octet. The netmask can be any number of bits. << 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.>> Also correct. Web servers generally have a feature called virtual hosting where multiple web sites map to the same IP address, and one server program handles all the sites. It indeed uses the incoming server name on the URL to decide which sites pages it should be serving at the moment. Paul
