I am running into an issue with with DNS on Windows Server 2012 R2 acting as Active Directory domain controller AND DNS server
I want to be able to setup certain records that will resolve internally using the local DNS server but if record is not present, the request is sent for external DNS query. Is this possible with Windows Server 2012R2?
[internal records managed by windows server 2012 DNS server]
sub1 A 10.10.0.1 sub2 A 10.10.0.2 sub3 CNAME sub1.something.com.
[external records managed by external DNS provider]
sub4 A 18.104.22.168 sub5 A 22.214.171.124 sub6 CNAME images.cdnprovider.net.
So basically i want to be to direct users to internal resources if requesting the records(for example sub1.something.com, sub2.something.com and sub3.something.com) in the internal DNS and if those records do not exist (for example sub4.something.com, sub5.something.com and sub6.something.com) then it should go out and resolve appropriately
I am trying to do this so i don't have to copy all records from external DNS provider to internal DNS. So that way i only add the records that need to be resolved locally and for the ones not added locally then it should go out and resolve.
Can i do this?
If my question is not very clear please let me know and i will edit it right away.
UPDATED: Basically something that works same way hosts file work on Windows OS(and others as well), where if the records are present then it uses local host records and if not it goes out.
