When you have a few domains with different extensions and you want all of them to open the same Internet site, you can have the Internet site under one of them and forward the rest. There are several approaches to redirect one Internet domain name to another, including the so-called domain parking. When your hosting package permits it, though, it'll be better if you host all the domains and set up a URL redirect, not a domain redirect. The real difference between the two is that while a domain address is hosted, you could still have content for it, create subdomains, e mail addresses, etc., while with a parked domain you cannot do any of these things. As an example, if you are building localized Internet sites under different country-code Internet domain names, you'll be able to work on them, but meanwhile, visitors shall be forwarded to the primary site.
