Domain Aliases

From Ezee.co.uk

A domain Alias is simply another domain name mapped directly to your primary domain.

For example if your company is called Johns Widgets and your domain name is johnswidgets.co.uk but you wanted to add the .info version of the domain name you could do this using the Alias facility. This would mean that visitors could type in either johnswidgets.co.uk or johnswidgets.info and it would go to exactly the same space.

This feature is handy as it means you don't have to pay for multiple hosting accounts if all you want to do is host the same site for multiple domains.
