When you have several domains with different extensions and you want all of them to open the same Internet site, you could have the site under one of them and redirect all the rest. There are a number of approaches to redirect one Internet domain name to another, among them the so-called domain parking. When your 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 main difference between the two is that while a domain address is hosted, you could still have content for it, set up subdomains, e-mail addresses, and so on., while with a parked domain you cannot do any of those things. As an illustration, if you are building localized Internet sites under different country-code domains, you'll be able to work on them, but in the meantime, visitors will be redirected to the primary website.
