In case you have a few domains with different extensions and you need all of them to open the same Internet site, you could have the site under one of them and forward the others. There are a number of methods to redirect one domain name to another, including the so-called domain parking. When your website hosting plan permits it, though, it shall be better if you host all of the domains and set up a URL redirect, not a domain redirect. The primary difference between the two is that while a domain is hosted, you can still have content for it, create subdomains, e-mail addresses, and so forth., while with a parked domain you are unable to do any of those things. For example, if you're building localized Internet sites under several country-code domain names, you shall be able to work on them, but at the same time, people will be forwarded to the primary website.
