If you have several domains with different extensions and you need all of them to open the exact same website, you could have the Internet site under one of them and redirect the rest. There are a number of methods to redirect one domain name to another, among them the so-called domain parking. If your website hosting package permits it, though, it'll be better if you host all of the domains and create a URL redirect, not a domain redirect. The main 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 so on., while with a parked domain you are unable to do any of these things. As an illustration, if you're building localized sites under different country-code Internet domain names, you shall be able to work on them, but in the meantime, visitors will be redirected to the primary Internet site.
