When you have several domain names with different extensions and you need all of them to open precisely the same Internet site, you could have the Internet site under one of them and redirect the rest. There are several approaches to redirect one domain to another, among them the so-called domain parking. When your website hosting plan allows it, though, it'll be better if you host all the domains and create a URL redirect, not a domain redirect. The primary difference between the two is that while a domain address 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. For instance, if you are building localized websites under different country-code domains, you shall be able to work on them, but at the same time, visitors will be forwarded to the main site.
