A domain is simply the web address that you type into your browser and you get the desired page. For instance you would type domain name in your browser to go to the web site. The most common extensions are ".com - .net - .org.", however there are many more are available like .biz. Today, domain names are easy and affordable to reserve but taught to get the perfect name. The average price for a domain is anywhere from $10 to $50. Domain names are officially managed by the worldwide organization ICANN (The Internet Corporation for Assigned Names and Numbers). When you purchase a domain name you purchase it through a registrar that has been accredited by ICANN. Many web hosts (ISP) will help you to reserve domain name for you, but the advantage to reserving your domain through a pure domain registrar is the best way and you will get the actual price. You can use two words with - sign between them to make it different.
