If you have a few domain names with different extensions and you want all of them to open the very same Internet site, you may have the Internet site under one of them and forward the rest. There are a number of approaches to redirect one domain to another, like the so-called domain parking. If your web hosting package permits it, though, it'll be better if you host all the domains and create a URL redirect, not a domain redirect. The main difference between the two is that while a domain is hosted, you may 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. As an illustration, if you are building localized websites under several country-code domains, you shall be able to work on them, but in the meantime, people will be forwarded to the primary Internet site.
