Different Domain Name Types

From Lunarpages Web Hosting Wiki

What is the difference between a subdomain, parked domain and addon domain? Each are unique ways for a visitor to make his or her way to your web site. What makes them different though?

Subdomains

A subdomain is a domain that has been prefaced with additional parts. This is often useful when you want to share the same main domain among parts of a web site, but you do not wish to change the entire domain name. An example of this would be blog.lunarpages.com or support.lunarpages.com. These are both important parts of the base lunarpages.com web site but have been moved to separate sections for both ease of organization and management. They are still under the lunarpages.com domain though, so people know to associate them with Lunarpages web hosting.

Parked Domains (Aliases)

A parked domain name would be one that is placed on top of a location. As an example, lets say I own both mydomain.com and mydomain.net. The domain mydomain.com is my main domain, but I can park mydomain.net on top of it so that anybody going to mydomain.com or mydomain.net will both be sent to the same server location where my web site is stored.

Addon Domains

Addon domains are a unique feature we offer our clients here at Lunarpages. On the Basic, Business and Windows hosting plans they give you the ability to host more than one domain from the same web hosting account. As an example, if you want to host both your baseball fan site and your hockey web site here with Lunarpages, you would not be required to get two separate hosting accounts. You could add one on as an addon domain to the other and host both from the same spot.
