Sub & Add-On Domains
Sub Domains:
A sub domain, also known as a third-level domain, is a very good way to create memorable web addresses for various sub-sites of your website. For example, Google uses sub domains for its different services, examples of sub domains include:
maps.google.com, news.yahoo.com, video.google.com etc.
The basic syntax is: http://subdomain.domain.com. Sub domains can be used effectively to establish branding and promote new products and services. For example, a chain store may establish sub-domains for different cities, or a university can set up sub domains for different academic programs. Traffic from sub domains can also be redirected to different sites or sub domains.
Add-On Domains:
If you have a website established and wish to set up another the most cost effective way is to use add-on domains. This method allows you to make the most of your web space and available bandwidth. You can add on domains to your original hosting account, this will ensure that you make the most of your available space without paying out for additional accounts.
An add-on domain is a new domain name that points to a subdirectory within your existing domain hosting account, where the website for the new domain will reside. Add-on domains must be registered domain names that you own, and that are configured to point to your web host’s servers.
From a web user perspective, an add-on domain functions just like any other domain. For example, if you already have a hosting account under www.maindomain.com, you can register and set up an add-on domain (for example: www.addondomain.com), so that when your visitors type http://www.addondomain.com in their browser, they will be transported to the new site, allowing for site individuality.
Statistics for add on domains are also available as individual sites on your hosting control panel. Utilizing add on domains is the most effective method of creating multiple individual websites.
Parked domains, add-on domains, sub-domains and URL forwarding can all be set up and overseen from your control panel of your hosting account.
