A domain name or domain is a structured label which is connected to a specific IP (Internet Protocol) address of a server where the web page is being hosted. Here’s an example: http://www.maheshtechnology.com is a domain name.
Registering a domain name does not automatically activate a website that displays when visitors enter your domain name into a Web browser. The domain name must have a hosted website that includes a numeric address, called an IP address, for visitors to access the website using your domain name.
