If you have several domain names with different extensions and you want all of them to open the exact same website, you can have the site under one of them and forward all the rest. There are a number of approaches to forward one Internet domain name to another, such as the so-called domain parking. When your hosting package allows it, though, it'll be better if you host all the domains and create a URL redirect, not a domain redirect. The primary difference between the two is that while a domain name is hosted, you may still have content for it, set up 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 sites under different country-code domains, you'll be able to work on them, but at the same time, visitors will be forwarded to the main Internet site.
