I'm in a quandary.
I need to implement Split-Horizon DNS in my office based on subnet. For example:
- Users in 10.170.0.0/16 need to resolve "srv01.extra.company.com" to
- Users in 10.180.0.0/16 need to resolve "srv01.extra.company.com" to
- Others in 10.0.0.0/8 need to resolve "srv01.extra.company.com" to 10.25.0.5
Now, this is easy to implement using BIND. Unfortunately, my network is based on Active Directory; I can't possibly change the DNS Servers of all workstation to just point to the BIND server, can I? They need to be pointing to Domain Controllers.
I had been playing with the idea of using stub zones or conditional forwarders, but based on my understanding, those methods will make the Domain Controllers to perform the DNS resolution themselves, instead of having the workstations contact the relevant nameservers.
What can you suggest to help solve this split-horizon problem?
- The AD FQDN is actually
id.company.com, not company.com.
- I made a mistake on the IP addresses above. Fixed.
