BIND9 Forwarding Reverse DNS
Solution 1:
Please add a 'forward only;' statement to the forwarded zones:
zone "24.172.in-addr.arpa" {
type forward;
forward only;
forwarders {
172.24.16.10;
172.24.16.11;
};
};
If that doesn't make a difference, check if the name servers 172.24.16.10; 172.24.16.11 actually respond.
