An IP address is a unique string of numbers seperated by periods that identifies each computer using Internet Protocol to communicate ofver a network. A subnet mask is used to divide an IP address into twoparts. One part identifies the host, the other part identifiesthe network to which it belongs to.
The domain name is the part of a network address that identifies it as belonging to a particular domain. The domain name functions as a link to the IP address. Links do not contain actual information, but they do point to the place where the IP address information resides. The IP address is the actual code and the domain name is the nickname for that code.
HTML stands for hypertext markup language.
