What is a Sub-Domain?

A subdomain, also known as a "third-level" domain, is a great way to create memorable web addresses for various sub-sites of your site. For instance, Yahoo! uses subdomains for its different services, like "mail.yahoo.com", "music.yahoo.com", etc. The basic syntax is: "http://subdomain.domain.com".

Large businesses use subdomains to establish branding and focus on separate products or services, because a subdomain creates a separate URL and web presence, all within your same main hosting account. For example, a restaurant directory may establish sub-domains for different cities, or a school can set up subdomains for different academic programs.

It is also possible to redirect (forward) traffic from a particular subdomain to another location, either within the main site or to a different website altogether.

You should be able to set up and manage add-on domains, parked domains and subdirectories from your hosting account or domain registrar control panel. However, as we usually suggest, always consult with your web host before proceeding if you have any doubts.
