It's simply the hostname. With Brinkster, they will have several machines hosting the websites so they number each machine.

Thats correct, most large sites load balance which means that when you connect you will be sent to a particular machine in their system, most people hide this so you only see the www.name.com but sometimes the full name appears.

Hi these are called Subdomains, they are only called www9 because of choice. Just like there is websites called:

http://hd.sky.com thats because sky created the subdomain hd in their webserver settings. they could have called it www2 or xyz3 or just w.

WWW with a number is an illusion of a seperate domain when in fact it is a subdomain of an originial ordinary domain, like hd is a subdomain of sky.com www20 is a subdomain of brinkster.com and they could have called it anything they wanted.
