In case you have a lot of domain names with different extensions and you want all of them to open the same website, you could have the website under one of them and redirect all the rest. There are a number of ways to redirect one Internet domain name to another, among them the so-called domain parking. If your website hosting package deal allows it, though, it'll be better if you host all the domains and create a URL redirect, not a domain redirect. The real difference between the two is that while a domain is hosted, you could still have content for it, set up subdomains, email addresses, and so forth., while with a parked domain you can't do any of those things. As an illustration, if you are building localized Internet sites under various country-code domain names, you shall be able to work on them, but at the same time, visitors shall be forwarded to the primary site.
