Practically speaking, your Web Address is your Internet identity and your online brand. Your customers will remember this name and use it to find your Web site, your products or your services. And since no two parties can ever hold the exact Web Address simultaneously, your Internet identity is totally unique.
Technically, a Web Address is an addressing construct used for identifying and locating computers on the Internet. While computers use Internet Protocol (IP) numbers to locate each other on the Internet, people find them hard to remember. Therefore, Web Addresses were developed to permit the use of easily remembered words and phrases to identify Internet addresses.
For example, the Web Address jipl.net represents JIPL Web sites. When you type jipl.net into a Web browser or send e-mail to someone at jipl.net, the Domain Name System (DNS) translates jipl.net into the IP numbers used by the Internet and connects you to JIPL.
