When you have a number of domain names with different extensions and you need all of them to open the same website, you may have the Internet site under one of them and redirect the others. There are a number of approaches to forward one domain to another, such as the so-called domain parking. If your hosting package permits it, though, it'll be better if you host all the domains and create a URL redirect, not a domain redirect. The 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 so forth., while with a parked domain you cannot do any of these things. As an illustration, if you are building localized websites under different country-code Internet domain names, you shall be able to work on them, but at the same time, visitors shall be forwarded to the primary website.
