In case you have several domain names with different extensions and you want all of them to open the exact same Internet site, you can have the Internet site under one of them and redirect the others. There are various approaches to redirect one domain name 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 of the domains and set up a URL redirect, not a domain redirect. The main difference between the two is that while a domain address is hosted, you could still have content for it, create subdomains, e mail addresses, and many others., while with a parked domain it's not possible to do any of these things. For example, if you are building localized sites under different country-code Internet domain names, you'll be able to work on them, but meanwhile, visitors shall be redirected to the primary Internet site.
