In case you have a lot of domains with different extensions and you want all of them to open the same site, you may have the Internet site under one of them and redirect the rest. There are various ways to redirect one domain to another, such as the so-called domain parking. When your web hosting package deal allows it, though, it shall be better if you host each of the domains and create a URL redirect, not a domain redirect. The primary difference between the two is that while a domain name is hosted, you could still have content for it, create subdomains, e mail addresses, and many others., while with a parked domain it's not possible to do any of these things. As an example, if you are building localized websites under several country-code domain names, you'll be able to work on them, but in the meantime, people shall be redirected to the main website.
