Say there is a website, www.website1.com, that is hosted on a web server, web server A. Is it possible to have another website, www.something.website1.com on a different web server, web server B? Or is the www.something.website1.com still considered a sub domain of www.website1.com, and must be hosted on the same web server, A?
For clarification: www.website1.com is hosted on a third party web server, but a client wants us to host www.something.website1.com on one of our own web servers, NOT the third party. Is this possible?
