When choosing an Internet domain name you need to know the rules for Internet domain name registration. The Internet domain names extensions of .com, .info, .name, .net and .org TLDs are open and unrestricted. Traditionally, Internet domain registration extensions ending in .net have been used by organizations involved in Internet infrastructure activities . Domain Internet extensions of .org are frequently used for noncommercial organizations, and biz is reserved for use by businesses.
Domain names ending with .aero, .biz, .com, .coop, .info, .museum, .name, .net, .org, or .pro can be registered through many different companies (known as "registrars") that compete with one another. The Internet domain name registrar you choose will ask you to provide various contact and technical information that makes up the registration. This information will be submitted to a central directory called the registry. This registry is made available to other computers so that they may find the information necessary to send you e-mails and to find and visit your website.
When you register for an Internet domain name the information you provide will be made available to the public. Some registrars provide a service that allows you to privatize that information by having the registrar act as your proxy. Their information would be displayed for the public and not yours.
Your Internet domain registration will last anywhere from one year to ten based upon the options made available by your registrar. They have the flexibility to offer initial and renewal registrations in one-year increments, with a total registration period limit of ten years.
