When you have a number of domain names with different extensions and you need all of them to open the same Internet site, you may have the website under one of them and forward the rest. There are different methods to redirect one Internet domain name to another, including the so-called domain parking. If your hosting package allows it, though, it will be better if you host each of the domains and create a URL redirect, not a domain redirect. The main difference between the two is that while a domain is hosted, you can still have content for it, set up subdomains, e-mail addresses, and so on., while with a parked domain it's not possible to do any of these things. For example, if you are building localized sites under several country-code Internet domain names, you will be able to work on them, but in the meantime, visitors shall be redirected to the main site.
