BIND single cname to lookup through the forwarder
I have been setting up Zimbra in my local network. I setup BIND and setup a master zone eg example.com. I mapped the cnames to the ip of the servers as below.
example.com -> 192.168.1.10
zimbra.example.com -> 192.168.1.10
MX example.co -> zimbra.example.com
I use this as a secondary (for backup purpose). The real server is in cloud. that can be accessed with mail.example.com if I configured to use external DNS servers Eg 18.104.22.168 google DNS. Problem is if I enter mail.example.com in local i dont get server in cloud. I got it why! I can set the public IP of the mail server to mail.exaple.com. The server may change their IP address anytime. So the problem comes.
If there's anything can be done to get the IP of mail.example.com from a public DNS server?
can you post the "Zone config" for this secondary DNS server (example.com, zimbra.example.com ...)
and also "mail.example.com" if you have that on the same server?
I think you shouldn't have configured your primary DNS for mail.example.com on this server you have, so it will need to look up for it at the "root" servers (depends if you have configured it)
