In case you have several domain names with different extensions and you need all of them to open the very same site, you may have the site under one of them and redirect the rest. There are several ways to redirect one Internet domain name to another, including the so-called domain parking. When your hosting plan permits it, though, it'll be better if you host all 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, e-mail addresses, and so on., while with a parked domain you cannot do any of those things. For instance, if you are building localized websites under various country-code Internet domain names, you will be able to work on them, but at the same time, visitors shall be redirected to the main site.
