Hi, I do have a domain and a couple of different ip networks. E.g. domainname.de and 172.17.0.0/16 and 192.168.200.0/24 In our old dns files I only have a reverse master zone for the 172.17.-lans, but also 192.168.200.x addresses in the forward zone config. My question: dose maybe someone forgot the 192.168.200.x reverse zone files and config and can I just create a file like that for the 172.17 hosts and adding the config for the reverse zone to my named.conf? Any suggestions are welcome. Regards.
