If you have a number of domain names with different extensions and you need all of them to open the very same site, you may have the Internet site under one of them and redirect all the rest. There are various methods to redirect one domain to another, including the so-called domain parking. When your web hosting package deal allows it, though, it will be better if you host all 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 could still have content for it, create subdomains, e-mail addresses, etc., while with a parked domain you can't do any of these things. As an example, if you are building localized Internet sites under different country-code Internet domain names, you will be able to work on them, but at the same time, visitors will be forwarded to the main site.
