A domain name tells people (and the computers they use) how to find your home page on the Internet. Your hosting provider assigns each domain name to a numerical IP (Internet Protocol) address. People remember names better than numbers, but computers translate your domain name (in the form of "www.yourname.com") into IP address numbers like 18.104.22.168.
Registering a domain name for your business or organization is essential to your marketing efforts. A domain gives your business credibility and a unique identity on the World Wide Web.
Before registering a domain name you will first have to do a Whois search to see if the requested domain name is available. This service is performed for you automatically by most domain registration sites at the time of registration.
