ispCP on local machine?

You should know what's the servername - maybe you can choose a new one (e.g. server-new.yourdomain.tld) and then you can work with this FQ-hostname.
Of course you have to add this host in the dns-zone....

And also - the URL you want to use for the panel (eg. adminpanel.yourdomain.tld) - you can use this.

And with this you may install the domains - you can test the website 1 with vu2001.adminpanel.yourdomain.tld).

Everything else is a task of "move-management" :-)
