One more question:
In ISPConfig > Management > Server > Settings > DNS,
i have to mention two DNS-servers:
Default Ns1: ?
Default Ns2: ?
Which DNS-servers have i have to mentioned here,
the IP-address of my own server, which runs Bind9 or
the DNS-resolvers provided by the network of the colocation?
These DNS Servers where used as defaults in the ISPConfig DNS-Manager. So you should enter the domain of your server as ns1 and the domain of the secondary server that you want to use as ns2.
