In case you have a number of domain names with different extensions and you would like all of them to open exactly the same site, you can have the website under one of them and forward the rest. There are different ways to redirect one Internet domain name to another, including the so-called domain parking. When your hosting plan permits it, though, it'll be better if you host all the domains and create a URL redirect, not a domain redirect. The difference between the two is that while a domain name is hosted, you can still have content for it, create subdomains, e-mail addresses, etc., while with a parked domain you can't do any of those things. As an example, if you're building localized sites under different country-code Internet domain names, you shall be able to work on them, but meanwhile, visitors shall be forwarded to the primary website.
