If you have a lot of domain names with different extensions and you want all of them to open exactly the same site, you could have the Internet site under one of them and forward all the rest. There are a number of approaches to redirect one domain name to another, including the so-called domain parking. When your hosting package deal allows it, though, it'll be better if you host each of the domains and create a URL redirect, not a domain redirect. The difference between the two is that while a domain is hosted, you could still have content for it, set up subdomains, email addresses, and so forth., while with a parked domain you cannot do any of these things. For example, if you're building localized Internet sites under several country-code domains, you'll be able to work on them, but at the same time, people shall be redirected to the primary website.
