In case you have several domains with different extensions and you would like all of them to open the same Internet site, you could have the Internet site under one of them and forward the others. There are various methods to forward one Internet domain name to another, among them the so-called domain parking. When your website hosting plan allows it, though, it'll be better if you host each of the domains and create a URL redirect, not a domain redirect. The real difference between the two is that while a domain name is hosted, you could still have content for it, create subdomains, e-mail addresses, and many others., while with a parked domain you can't do any of these things. For instance, if you're building localized Internet sites under different country-code domains, you'll be able to work on them, but meanwhile, people will be forwarded to the main site.
