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