A domain is a name that identifies IP addresses on the internet. The domain name Yahoo.com represents about fifteen (15) IP addresses. Domain names are used to identify Web pages. For example, in the URL http://www.gohome.com/index.html, the domain name is gohome.com. You register a domain name by registering with a domain name services registrar. The domain name
industry is regulated and overseen by ICANN, which is an organization responsible for providing standards and procedures for certifying companies as domain name registrars.
Domain name registration has grown over the years. Network Solutions was the first domain name registrar to ever provide such a service. That was over ten years ago but today there are many accredited registrars. Only a domain name registrar is permitted to access and modify the master database domains that are on InterNIC servers. The fee is determined by the registrar as far as getting a
domain name and some registers have special domain name packages.
