Installation of ispCP via SSH

[ServerQuack]

Well, I'm looking at these two pages here, and the problems begin:

http://isp-control.net/documentation/sta...ion/debian
http://isp-control.net/documentation/howto/hostname

I've had servers before and I've never had a domain assigned to me in the past since I always had my own domains to begin with. When I signed up for the vServer I was only issued an IP number ... as has been the case every time that I had a server in the past. Even my last hosting service with cpanel assigned me a reseller account with an IP. So how can I make the installation work if I wasn't assigned a valid TLD to begin with? Don't get me wrong, I have several TLDs which belong to me ... but none of them have been pre-assigned to the server. I always thought that domains were added with the CP which would have to be installed to begin with ???
Now I'm thoroughly confused about this TLD issue as an installation requiremement ...
