Hi
I am trying to understand bind9 more thorughly.
Backstory: We have been using bind9 for a long time and overhauling it
for more "usage".
We have been using a "hidden master dns" logic with views for different
usages.
E.g. Client -> Slave DNS Server <- (Transfer zones from hidden master)->
Hidden Master.
We had two views "external" and "internal" and now we added a new view
"dmz" aswell.
In one of those zones we had an interesting DNS "thingy" where for
example a CIDR 192.168.100.0/24 was generating entries to the main
"hidden dns" server via includes. It uses a domain called example.com.
Now another DNS server created DNS entries for the same CIDR
192.168.100.0/24 but it had a different domain "subdomain.example.com".
Including that info was easy.
In the Slave DNS
zone "example.com" {
file blaah
type slave
masters { main_hidden_dns_server }
}
zone "subdomain.example.com" {
file blaah
type slave;
masters { other_dns_server }
}
But now comes the problem. When generating a PTR record
100.168.192.in-addr.arpa, I wish to combine both of these "results" into
one lookup. How can I do that? I tried to add:
zone "100.168.192.in-addr.arpa" {
file blaah
type slave;
masters { other_dns_server }
forward first;
forwarders { main_hidden_dns_server }
}
But this forwarding logic doesnt work. I have a feeling the forwarding
only works specific zones. and you can't combine two of the same
"names" into one. Am I correct and in order for PTR records to work I
need to get them into a single file?
