easier Internet use. When you type in a Uniform Resource Locator URL (e.g.
http://www.yahoo.com) into the address bar of your browser, your Internet Service Provider
(ISP) looks for the IP address that is associated with this address. Once your ISP finds
the IP address required, it communicates it to your browser which in turn takes you to the
Web page located at that IP address.
