Newbie question: what is my server name?

how do I know what server I'm on? is it shown somewhere in the DH control panel?

thx,

It should have said in your "welcome email", but you can check on the Control Panel. A good place to get a lot of information is by clicking "Account Status" in the top right-hand corner of the panel (including your server).

ping your domain name.
If you have shell access, ssh to your domain name. It may show host name, or you can give hostname command.
