When you have a few domain names with different extensions and you need all of them to open the exact same site, you may have the Internet site under one of them and forward all the rest. There are a number of ways to redirect one Internet domain name to another, among them the so-called domain parking. When your hosting package allows it, though, it shall be better if you host each of the domains and create a URL redirect, not a domain redirect. The real difference between the two is that while a domain name is hosted, you may still have content for it, set up subdomains, email addresses, and many others., while with a parked domain you cannot do any of those things. For example, if you are building localized sites under various country-code domain names, you will be able to work on them, but meanwhile, people shall be forwarded to the primary site.
