When you have a lot of domain names with different extensions and you would like all of them to open the same site, you could have the Internet site under one of them and redirect the others. There are different approaches to forward one domain to another, such as the so-called domain parking. When your web hosting plan allows it, though, it'll be better if you host each of the domains and create 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, set up subdomains, email addresses, and many others., while with a parked domain you are unable to do any of those things. As an illustration, if you're building localized sites under various country-code Internet domain names, you'll be able to work on them, but meanwhile, visitors will be forwarded to the main website.
