In case you have a lot of domains with different extensions and you would like all of them to open the exact same website, you may have the Internet site under one of them and redirect the others. There are various approaches to forward one domain to another, like the so-called domain parking. If your hosting package deal allows it, though, it shall be better if you host all of the domains and set up a URL redirect, not a domain redirect. The primary difference between the two is that while a domain name is hosted, you could still have content for it, set up subdomains, e mail addresses, etc., while with a parked domain you are unable to do any of those things. For example, if you are building localized Internet sites under various country-code domain names, you shall be able to work on them, but in the meantime, people will be forwarded to the primary site.
