When you have a lot of domain names with different extensions and you want all of them to open precisely the same Internet site, you may have the site under one of them and redirect the rest. There are several methods to forward one domain to another, including the so-called domain parking. If your web 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 name is hosted, you can still have content for it, create subdomains, email addresses, etc., while with a parked domain you can't do any of these things. For instance, if you're building localized Internet sites under various country-code Internet domain names, you shall be able to work on them, but at the same time, people will be redirected to the main site.
