If you have several domain names with different extensions and you would like all of them to open precisely the same website, you could have the Internet site under one of them and redirect the others. There are a number of ways to redirect one domain to another, among them the so-called domain parking. When your hosting package allows it, though, it shall be better if you host all of the domains and set up a URL redirect, not a domain redirect. The primary difference between the two is that while a domain is hosted, you may still have content for it, create subdomains, email addresses, and so forth., while with a parked domain you can't do any of these things. For example, if you are building localized websites under different country-code Internet domain names, you will be able to work on them, but meanwhile, visitors will be forwarded to the primary site.
