If 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 site under one of them and redirect all the rest. There are different ways to forward one Internet domain name to another, among them the so-called domain parking. If your website hosting package deal allows it, though, it will be better if you host all of the domains and create a URL redirect, not a domain redirect. The difference between the two is that while a domain name is hosted, you could still have content for it, create subdomains, email addresses, and so forth., while with a parked domain you are unable to do any of those things. As an example, if you are building localized websites under several country-code domain names, you shall be able to work on them, but meanwhile, visitors will be redirected to the main website.
