As another problem I can point to asking the host name (a valid one) during the installation of ISPConfig(I do not want to assign valid name at the moment).
This are some different questions. You can use the IP for everything except the apache vhosts, they are name based and you must have a correct DNS A-Record pointing to your server or modify the hosts file.
There are several threads in the forums on how to install ispconfig without providing a domain. In the installer, leave the host empty and enter the IP-Address as domain.
