When you have a few 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 all the rest. There are a number of ways to redirect one domain name to another, including the so-called domain parking. If your 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 address is hosted, you could still have content for it, create subdomains, email addresses, and so on., while with a parked domain it's not possible to do any of those things. For example, if you're building localized Internet sites under several country-code Internet domain names, you will be able to work on them, but meanwhile, visitors will be redirected to the main website.
