Which is NOT a delegation of 160.10.10.IN-ADDR.ARPA.
$ORIGIN does NOT change the current owner. You actually
delegated whatever the current owner name is.
My first thought would be. Kill the forward zones as
you are authoritative for 10.10.IN-ADDR.ARPA.
Make sure you have a empty forwarders declaration for
10.10.IN-ADDR.ARPA.
e.g.
zone "10.10.IN-ADDR.ARPA." {
type master;
file "10.10.IN-ADDR.ARPA";
....
forwarders { /*empty */ };
};
This will override any global forwarders and allow named
to follow the delegations in 10.10.IN-ADDR.ARPA.
Don't use $ORIGIN in the master file for 10.10.IN-ADDR.ARPA.
If you need to had individual PTR records use 2 labels.
e.g. the reverse of 10.10.3.4 is:
4.3 PTR foo.example.net.
While named has lots of features people tend to over use
them. This especially applies for forward zones and $ORIGIN.
