When you have a number of domains with different extensions and you would like all of them to open the exact same website, you can have the Internet site under one of them and redirect the rest. There are various approaches to forward one domain to another, like the so-called domain parking. If your hosting package deal permits it, though, it'll be better if you host each 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 may still have content for it, set up subdomains, e mail addresses, and so forth., while with a parked domain you are unable to do any of these things. As an illustration, if you're building localized websites under different country-code Internet domain names, you'll be able to work on them, but meanwhile, people shall be redirected to the primary Internet site.
