Great, it is solved! It was the zone file: Replaced $TTL 86400 caluta.carsten.peters.name. IN SOA carsten.peters.name root ( With $TTL 86400 @ IN SOA carsten.peters.name. root ( it was probably the missing trailing dot. AND caluta IN NS 192.168.1.3 caluta IN A 192.168.1.3 kutter IN A 192.168.1.2 With IN NS caluta.carsten.peters.name. caluta IN A 192.168.1.3 kutter IN A 192.168.1.2 no forward necesary in /etc/named.conf for the server is already a caching server. No reserve zone for carsten.peters.name, well I think if I don't contact servers that require a reserve lookup I can probably do without it Anyway, I will put the reserve zone later. Thank you, Carsten
