If you have a number of domain names with different extensions and you want all of them to open the exact same Internet site, you could have the Internet site under one of them and forward all the rest. There are various ways to redirect one domain name to another, like the so-called domain parking. When your web hosting package deal allows it, though, it will be better if you host each of the domains and set up a URL redirect, not a domain redirect. The real difference between the two is that while a domain address is hosted, you could still have content for it, set up subdomains, e mail addresses, and so on., while with a parked domain you cannot do any of those things. For example, if you're building localized websites under different country-code Internet domain names, you'll be able to work on them, but at the same time, people will be forwarded to the primary Internet site.
