how to register www-examplesite.com domains

[spiritualseo]

I saw a site today using www-examplesite.com. There is another variation of the site with the name www.examplesite.com which already exists.. I was wondering how to register this www-examplesite.com? and what are its advantages?

Similarly, how do I book up a www2.examplesite.com domain?

Guys forget about the first question. I got the idea.. how about www2.sites?

www2 dot and other variations are simply subdomains.

You'll either have to setup each subdomain in your DNS or setup a wildcard DNS entry (e.g., *.examplesite.com).

Then you'll need to configure your web server.
