If you have a number of domain names with different extensions and you would like all of them to open the exact same website, you could have the Internet site under one of them and forward the others. There are a number of methods to redirect one domain name to another, like the so-called domain parking. If your web hosting package deal allows it, though, it'll be better if you host all the domains and set up a URL redirect, not a domain redirect. The real difference between the two is that while a domain is hosted, you could still have content for it, create subdomains, e mail addresses, and so forth., while with a parked domain you can't do any of these things. For example, if you are building localized Internet sites under various country-code Internet domain names, you shall be able to work on them, but meanwhile, people will be forwarded to the primary site.
