If you have a number of domain names with different extensions and you would like all of them to open the exact same website, you can have the website under one of them and redirect the rest. There are several ways to forward one Internet domain name to another, including the so-called domain parking. When your web hosting plan permits it, though, it shall 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, create subdomains, email addresses, etc., while with a parked domain you can't do any of these things. For instance, if you are building localized sites under several country-code Internet domain names, you shall be able to work on them, but at the same time, people shall be redirected to the primary site.
