In case you have a few domain names with different extensions and you would like all of them to open precisely the same Internet site, you could have the site under one of them and redirect the others. There are a number of methods to forward one domain name to another, like the so-called domain parking. If your web hosting package deal permits it, though, it will be better if you host each of the domains and set up a URL redirect, not a domain redirect. The main difference between the two is that while a domain address is hosted, you can still have content for it, create subdomains, email addresses, etc., while with a parked domain you can't do any of these things. As an illustration, if you're building localized Internet sites under various country-code domain names, you'll be able to work on them, but meanwhile, visitors will be redirected to the main Internet site.
