When you have a few domain names with different extensions and you need all of them to open the same Internet site, you may have the website under one of them and redirect the others. There are different approaches to forward one domain to another, including the so-called domain parking. If your hosting package allows it, though, it will 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 name is hosted, you could still have content for it, set up subdomains, e-mail addresses, and so on., while with a parked domain you are unable to do any of these things. For example, if you're building localized Internet sites under several country-code domains, you shall be able to work on them, but meanwhile, visitors shall be forwarded to the main Internet site.
