Host4Cheap Hosting allows you to host unlimited domain names on your account without any additional charges. Each domain name can have its own content or all domains can be set to serve the same site - you have full flexibility and control. Being able to host unlimited websites on just one hosting account can save you a lot of money!

Parked Domain
This is very useful if you buy the same domain with different extensions.
eg mydomain.com & mydomain.co.uk & mydomain.net
These could all be parked onto your existing domain giving you complete brand protection, but you only have to maintain a single website.
If your domain was mydomain.net, and you then parked mydomain.com on top,
http://mydomain.com/shop/ & http://mydomain.net/shop/ would open exactly the same page.
