I have BIND9 server that is serving some local zones (for dev environment). Now I need to be able to merge the content of the local zone with the "remote" zone for the same zone:
host1 IN A 10.0.1.100. host2 IN A 10.0.1.101.
www IN A 18.104.22.168. mail IN A 22.214.171.124. host1 IN A 126.96.36.199.
As a result, I need to "merge" local with remote, giving preferences to the local records (hence
host1 will get the address
www IN A 188.8.131.52. mail IN A 184.108.40.206. host1 IN A 10.0.1.100. host2 IN A 10.0.1.101.
And if I change anything on the remote zone - it should resolve it correctly, like: if there's no such record in the local zone - try the remote one using
Looks like mix of forwarders and local zone.
