Im doing an assignment for DNS on Ubuntu 10 using BIND9. Everything is on an internal network with private IP addresses and not access to the internet. I have set up my own root name server (.) and a top level domain server (com). I also have another server configured for example.com. In the root name server's zone file I have the A record for the TLD server (com) and when I do "nslookup com" I get the address of the root name server and then the correct address of the com server. When I do "nslookup example.com" I get the output "server cant find example.com: NXDOMAIN". What I want to do is when I do "nslookup example.com" I want it to return the IP address of the top level domain (com) server. I dont want to include the A record of example.com in the root zone file because then it will give me the address of example.com and not com. Can any please tell me how I can do this? Here is the zone file of my root name server: $TTL 604800 $ORIGIN . @ IN SOA root.net. root.root.net. ( 1 ; Serial 604800 ; Refresh 86400 ; Retry 2419200 ; Expire 604800 ) ; Negative Cache TTL . IN NS root.net. root.net. IN A 172.16.2.10 com. IN A 172.16.2.11
