I have read DNS and Forward Lookup Zones but I did not fing the aswer there.
I have Microsoft Domain with Active directory server , and DNS server for internal use. My local domain called example.local and it is managed by this server. I need to be able to add locally example.com (Which managed by external public DNS server like GoDaddy), But I need the local DNS server to forward the lookup in case of unexist record.
For example: on the public DNS server i have www.example.com -> 220.127.116.11
on the local DNS I have mail.example.com -> 18.104.22.168
Now, I need to be able to lookup both www and mail.example.com from Internal (It is OK of course to lookup only www from external), But I do not want to overwrite it, I want to put only mail.example.com on the local and that the DNS server will forward it to the ISP DNS.
Is it possible?
