I have solved the topic by modifying the behavior of the DNS Cache with Forwarding Mode.
I just make the dns cache in forwarding mode, by placing the FORWARDONLY Variable into the /env directory. Then I edited the @ File to look first at the internal DNS Server, then to my other DNS Server, then to my ISP DNS Server. (Placed the IP Numbers in it) So my problem is solved. People can now create a dummy domain for testing and do not have to enter manually the IP's in the /root/servers directory But thanks for the answers anyway, it was a pleasure.. Best Robert PS: But I probably work on the code (and be finished in 10000 Years), maybe I succeed in maintaining a DNSCACHE with the current webinterface. I think about adjusting the behavior of the DNSCACHE (FORWARD,NON-FORWARD, separate Domains pointing to several DNS Servers, external cache,....
