Domain names are addresses on the Internet, like expedia.com or aol.com. Domain names are like street addresses or telephone numbers and, in general, function in the same way. They tell where you are located or how to reach you on the Internet, but they do not act as identifiers of the source of goods and services. However, where domain names are used as something other than merely an address, they may become trademarks. For example, where the name EXPEDIA is splashed across the home page in stylized letters, it is clear that it is being used to identify the source of specific travel services, and therefore it acts as a trademark.
