What is a SubDomain? Print

  • 0

A subdomain is a domain that is part of a larger domain, based upon a prefix name of your choice. For example, the example.com domain might have a subdomain support for the support department that directs visitors to a separate area of the web site. If the subdomain prefix is support, then the fully qualified domain name (FQDN) is support.example.com.

You can use subdomains whenever you want to create separate areas on your web site that are accessible using different FQDNs.

Examples of some typical uses of Subdomains:

  • Organizing Departments: For businesses that operate different departments, giving each department a subdomain make it easier to manage its web presence. (i.e. using Sales.Example.com for the Sales Dept.)
  • Languages: Subdomains are used to provide alternate versions of your website according to a visitor’s language preference. (i.e. using Sp.Example.com for the Spanish Language)
  • Localization: If your website represents multiple geographic locations, each with its own unique web presence, then subdomains can provide each location its own independent version of your site.  (i.e. using Texas.Example.com for the State of Texas location)
