What is sub-domain?

Sub-domain

A sub-domain is an easy way to create a memorable Web address for unique content areas of your site.

In the Domain Name System (DNS) hierarchy, a sub-domain is a domain that is part of a larger domain. For example, "example.com" is a sub-domain of the "com" top-level domain (TLD) and "www.example.com" is a sub-domain of "example.com". In fact, the "com" TLD is a sub-domain of the root domain, "."

Relative to a sub-domain, the larger domain that it is a part of is its parent domain, or alternately superdomain (the former term appears to be preferred by the IETF).



A sub-domain is sometimes termed a vanity domain, especially when it is a sub-domain of an ISP's own domain aliased to an individual user account. However, the term "vanity domain" has other usages, discussed at that article.

A sub-domain is a second website, with its own unique content, but there is no new domain name. Instead, you use an existing domain name and change the www to another name. The sub-domain name looks like forums.domain.com, help.domain.com, help2.domain.com.

To create a sub-domain, you need to follow this:

Login to cPanel and click Sub-domains.
In the drop-down, choose the domain.
In the box before the domain, type the sub-domain name you want.
Click inside the "Document Root" box and it will auto-fill.
Hit the Create button.

To delete a sub-domain, you need to follow this:

Login to cPanel and click Sub-domains.
At the bottom, under Actions, click Remove.
