When you have a lot of domains with different extensions and you would like all of them to open the same site, you may have the Internet site under one of them and redirect the rest. There are several ways to redirect one domain name to another, including the so-called domain parking. When your website hosting plan permits it, though, it shall be better if you host each of the domains and set up a URL redirect, not a domain redirect. The real 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 forth., while with a parked domain it's not possible to do any of these things. As an illustration, if you are building localized websites under various country-code domain names, you shall be able to work on them, but in the meantime, people shall be redirected to the main Internet site.
