What is Domain Name?

Domain Name

A domain name is a way to identify and lcoate computer connected to the internet. No two organizations have the same domain name. A domain name usually has two parts separated by periods called dot. E.g. Microsoft.com, intel.com. The last portion of the domain name is the top level domain name which describes the type of the organization.
  • Com – commercial entities
  • Edu – education institutions
  • Net – organization directly involved in Internet operations
  • Org – organizations
  • Gov- government entities
  • Mil – military entites
  • Country code- np for Nepal, uk- United Kingdom, Fr- France
Each domain name corresponds to an IP address. The DNS server is responsible for translation of domain names to IP address.

DNS is a name service that provides a standardized system for providing names to identify TCP/IP hosts as well as way to look to up the IP address of a host, given the host's DNS name. For example if you use DNS to look up the name www.ebay.com, you get the IP address of the WWW.EXAMPLE.COM Web Host:, Thus DNS allows you to access the website example.com by the name of www.example.cm instead of IP address. 

To provide a unique DNS name for every host computer on the Internet, DNS uses a time tested technique: Divide and Conquer. DNS uses a hierarchical naming system that's similar to how folders are organized hierarchically on a Windows computer. 


A Uniform Resource Locator specifies where an identified resource is available and the mechanism or retrieving it. In popular language, a URL is also referred to as a Web address.
URL represents a standardized addressing scheme for Internet resources and helps the users to locate these resources by indicating exactly where they are.
