Domain name registration is the act of reserving a name on the Internet for a certain period, usually one year. It is important to know that this domain will remain yours for as long as you renew it and there is no way to purchase a domain name forever. Domain name registration is necessary for a website, emails or another web service. The most important thing about a domain name registration is that it gives you personality and recognized identity. The price for a domain name registration varies greatly on its extension. For example, the most common .com is the most affordable one, while some country-specific domain name extensions are 5 times more expensive.
