Domain name is a name by which a website is identified. Each website has a domain name that serves as an address, which is used to access the website. A domain name consists of two parts. They are Toplevel domain(TLD) and Second Level Domain(SLD).

Top level domain.

A top-level domain can be called a domain name suffix. All websites will have a top level domain such as .com, .org, .in, .net , .gov , .edu  etc.The top-level domain helps identify the type of website which the domain name represents. For example, .com suffix (top level domain) is used by the commercial website, .org is used by websites of non-profit organizations. The domain along with the top level domain together form a domain name.

Second level domain.

A second-level domain is a part of the domain name which is found in the left of the top level domain. Let us consider http://www.wordpress.com as an example. Here “wordpress” is the second level domain and .com is the top level domain.

There are certain rules for creating a domain name. Some of them are:

  • It does not allow spaces.
  • Special characters are not allowed.
  • It is case sensitive, which means that a simple mistake can take you to wrong place.
  • Numbers can be used.

Every  Domain name is translated into IP address by DNS (Domain Name System).
