Domain registration is the process of securing your location, or your address on the web. You need a unique address (web address) and an IP address (numerical address of your site content). To register a domain name, companies and families looking to create a web site must contact a domain registrar.Domain registrars vary in their services offered, prices, and contract specifics. Some offer registration only, others also offer site building tools, email, and site hosting as well. Registration contracts with a domain registrar are typically in place for one year. Therefore, it pays to shop around for the services and features you need. When you register your site with a registrar service, they contact ICANN (Internet Corporation for Assigned Names and Numbers) to make the domain you have selected is available. The database used by ICANN is called the DNS (Domain Name Server) database. If the domain name is available and you opt to register it, the registration is logged by ICANN in the DNS database along with the unique IP address of your site host. This is where all your pages are located in cyberspace.As you complete the registration process, you?ll be asked to give your contact information, which will be available through the WHOIS database. The WHOIS database is a public access database that lists contacts for web sites. It also lists the expiration date of the domain name. Once a domain has expired, it becomes available for others to register.
