Each domain name or URL directs users to a specific IP address.
The domain can be found in the URL and is used in order to locate the website of a specific person or organization.
A domain can be divided up into three different elements: a subdomain, a domain name, and a top level domain (TLD).
Take about.1and1as an example: the 'about' element is the subdomain, the '1and1' element is the domain name itself and the '.com' part of the URL is the top level domain.
Gone are the days where you can only access the site when you are at home.
Now you can log in to your account anywhere and see what sexy singles are looking for someone like you!
