If you have a number of domains with different extensions and you need all of them to open exactly the same site, you may have the website under one of them and forward all the rest. There are different ways to redirect one Internet domain name to another, such as the so-called domain parking. When your web hosting package deal permits it, though, it shall be better if you host all of the domains and set up a URL redirect, not a domain redirect. The real difference between the two is that while a domain address is hosted, you can still have content for it, set up subdomains, e-mail addresses, and so on., while with a parked domain you cannot do any of those things. For instance, if you are building localized sites under several country-code domains, you will be able to work on them, but at the same time, visitors shall be redirected to the primary website.
