When you have a few domains with different extensions and you need all of them to open the same Internet site, you can have the website under one of them and forward the others. There are different methods to redirect one domain name to another, including the so-called domain parking. When your hosting plan permits it, though, it will be better if you host all the domains and set up a URL redirect, not a domain redirect. The real difference between the two is that while a domain is hosted, you may still have content for it, set up subdomains, e mail addresses, and many others., while with a parked domain you cannot do any of these things. As an example, if you are building localized websites under various country-code domains, you shall be able to work on them, but at the same time, people will be redirected to the primary site.
