When you have a lot of domain names with different extensions and you want all of them to open exactly the same site, you can have the site under one of them and redirect the others. There are a number of approaches to forward one Internet domain name to another, among them the so-called domain parking. When your hosting package permits it, though, it'll be better if you host each of the domains and set up a URL redirect, not a domain redirect. The main difference between the two is that while a domain address is hosted, you may still have content for it, create subdomains, email addresses, etc., while with a parked domain you can't do any of those things. As an example, if you're building localized Internet sites under various country-code Internet domain names, you'll be able to work on them, but at the same time, people shall be forwarded to the primary website.
