In case you have a lot of domains with different extensions and you would like all of them to open the exact same Internet site, you may have the site under one of them and forward all the rest. There are a number of methods to redirect one domain to another, among them the so-called domain parking. When your 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 address is hosted, you may still have content for it, create subdomains, email addresses, and so forth., while with a parked domain you can't do any of those things. As an illustration, if you're building localized sites under various country-code domain names, you'll be able to work on them, but at the same time, people shall be forwarded to the main Internet site.
