When you have a lot of domain names with different extensions and you want all of them to open precisely the same website, you may have the site under one of them and forward all the rest. There are several approaches to redirect one domain name to another, including the so-called domain parking. If your web hosting package deal allows it, though, it'll be better if you host all the domains and set up a URL redirect, not a domain redirect. The main difference between the two is that while a domain address is hosted, you may still have content for it, create subdomains, email addresses, and so on., while with a parked domain you cannot do any of these things. For instance, if you are building localized websites under several country-code domain names, you'll be able to work on them, but meanwhile, visitors will be forwarded to the main site.
