A domain name is an address seized by an Internet user to connect to a website (example: www.echo-stream.com).The address consists of the name of the site (Echo-stream) and the extension (.com), which can sometimes indicate the country (fr, ca) or the type of activity (com, gov, org, edu).

Name of the URL of your Internet address, domainname.com, is your only identifier on the Internet. It is a single unique name on the Web that no one else possesses it. Also it identifies your site so that visitors can access it online from anywhere in the world.

Example:
www.echo-stream.com
