When you have a number of domains with different extensions and you would like all of them to open the exact same site, you can have the website under one of them and redirect the others. There are different approaches to redirect one Internet domain name to another, including the so-called domain parking. If your web hosting plan permits it, though, it will be better if you host each of the domains and create a URL redirect, not a domain redirect. The primary 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 forth., while with a parked domain it's not possible to do any of those things. As an example, if you're building localized Internet sites under several country-code domain names, you shall be able to work on them, but meanwhile, visitors shall be forwarded to the main site.
