If you have several domain names with different extensions and you would like all of them to open precisely the same Internet site, you could have the website under one of them and forward the others. There are various methods to forward one domain name to another, including the so-called domain parking. If your web hosting plan allows it, though, it will be better if you host all the domains and set up 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, create subdomains, e-mail addresses, and so on., while with a parked domain you can't do any of those things. As an illustration, if you are building localized sites under various country-code domain names, you will be able to work on them, but meanwhile, people will be redirected to the main website.
