In case you have a number of domain names with different extensions and you would like all of them to open the same Internet site, you could have the website under one of them and forward the others. There are a number of methods to forward one domain to another, like the so-called domain parking. When your website hosting plan allows it, though, it shall be better if you host each of the domains and create a URL redirect, not a domain redirect. The difference between the two is that while a domain address is hosted, you may still have content for it, set up subdomains, e-mail addresses, etc., while with a parked domain you are unable to do any of these things. For example, if you're building localized websites under several country-code domains, you will be able to work on them, but in the meantime, visitors will be redirected to the main Internet site.
