If you ever wonder how in the world they do that, the answer is simple. This is made possible by using one of the Shared hosting features called “add-on domains.”

Today, many web hosting companies will offer you one or more free add-on domains with the hosting account you purchase from them. More often, a web hosting package allows you to have unlimited add-on domains, which means you can host any number of websites within your hosting account without paying additional fees. This is one way to inexpensively run several websites without spending a lot in hosting.

Signing up under a reseller hosting account is also a great way to host multiple websites on one account. At the same time, a reseller account will allow you to sell web hosting accounts to other webmasters. A reseller account running under Linux environment is provided with a Web Host Manager which you can use to set-up individual accounts for every customer. Within the Web Host Manager, you can add, modify and delete individual hosting packages that you want to sell. You are also free to set your own price, the space, bandwidth limit and the number of domains that can be hosted per hosting package.

If you decide to use it for personal use, it allows you to set-up an individual control panel for every domain name that you have.

Selling website hosting is also a great way to make money. That is the reason why a lot of online entrepreneurs already entered the web hosting business. A reseller account sometimes comes with many great features like unlimited email accounts and subdomains. The features that you get will depend on the kind of reseller plan you sign on with.

Hosting using Virtual Private Servers (VPS) and Dedicated Servers are also some other types of hosting that enable you to get more control over your hosting account and both types supports multiple domain hosting plus a lot more advantages than the shared hosting.

A Virtual Private Server for example, can be useful if you want to run an e-commerce site, host multiple domains, set-up an intranet and others.

Hosting under Virtual Private Server, unlike the shared hosting, would enable one to own and manage the hardware and all one have to do is to rent space and internet connection from the data center. Virtual Private Server is also called co-located server and is a very wise alternative if you are outgrowing your shared hosting plan.

The dedicated server on the other hand, is a single computer server which aims to support one's every need in a network. With a dedicated server, one can install and configure any program he wants. It is normally more expensive than a virtual private server plan and since you are in control of the server, you are also responsible for its installation and maintenance.

A dedicated server is designed for those who are experienced in administering their own network but can also be for those who are willing to learn.

Signing-up for a dedicated server hosting plan will allow one to fully customize or build his own dedicated server. One can also just choose and pay only for the features he needs. One advantage of having your own dedicated server is it doesn't put you on the risk of the server being congested because of other people's bandwidth unlike the shared hosting.

So before you sign-up for a web hosting account, it is important that you evaluate first your needs and then decide what kind of web hosting plan that fits for you.
