Differences between Aliases, Addon Domains, and Subdomains

Subdomain​

A subdomain 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 subdomain name looks like forums.domain.com, help.domain.com, help2.domain.com (assuming you already host domain.com).

Addon Domain An addon domain is a second website, with its own unique content. This type of domain does require you to register the new domain name before you can host it. So, if you want to host www.otherdomain.com, this is the solution. For additional information regarding addon domains, please refer to the following article:

Alias (Parked) Domain An alias

  • You need a place to park a domain for which you do not have a website
  • You have more than one domain that should lead to your primary domain
  • You have common misspellings of your domain name that you have registered
