I have managed to populate my
/etc/resolv.conf with several nameservers when I bring up my VPN. The nameservers have two zones of operation, internal (through the VPN) and public (Exposed). Some of the entries exist in both zones, but these point to different IP's, some only exists on the internal zone
Whenever I try to resolve some entry it defaults to the internal zone, which is a desired behavior, but, whenever I try to resolve an entry which does not exist on the internal zone I would like it to fetch the next available nameserver and query the same entry, basically if one nameserver does not know the answer ask the next one, if none have the answer then fail.
Is this possible to setup using
