When you have a few domain names with different extensions and you need all of them to open the very same site, you may have the website under one of them and redirect the rest. There are several ways to forward one Internet domain name to another, like the so-called domain parking. When your website hosting package deal permits it, though, it will be better if you host all 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, e-mail addresses, and many others., while with a parked domain it's not possible to do any of those things. As an example, if you're building localized Internet sites under several country-code Internet domain names, you will be able to work on them, but in the meantime, people will be redirected to the main site.
