When you have several domain names with different extensions and you would like all of them to open the very same Internet site, you can have the Internet site under one of them and redirect the others. There are various ways to forward one Internet domain name to another, such as the so-called domain parking. When your web hosting package permits it, though, it shall be better if you host all 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 can still have content for it, create subdomains, e-mail addresses, and many others., while with a parked domain you cannot do any of those things. As an example, if you're building localized sites under different country-code domains, you shall be able to work on them, but at the same time, visitors shall be forwarded to the main Internet site.
