When you have a lot of domains with different extensions and you would like all of them to open the very same Internet site, you can have the Internet site under one of them and forward all the rest. There are several ways to forward one Internet domain name to another, among them the so-called domain parking. When your website hosting package allows it, though, it'll be better if you host each 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 could still have content for it, set up subdomains, e-mail addresses, and so forth., while with a parked domain you can't do any of those things. For instance, if you're building localized sites under different country-code domains, you'll be able to work on them, but meanwhile, people shall be redirected to the primary website.
