If you have a number of domain names with different extensions and you want all of them to open the very same Internet site, you could have the Internet site under one of them and forward the others. There are several ways to forward one Internet domain name to another, like the so-called domain parking. If your website hosting package allows it, though, it'll 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, create subdomains, e mail addresses, and so forth., while with a parked domain it's not possible to do any of those things. For instance, if you're building localized sites under several country-code domain names, you will be able to work on them, but meanwhile, visitors shall be forwarded to the main site.
