Hi, I'm hoping someone can help with this question regarding DNS Forwarding:
I have an AD domain with 8 DNS servers across the country mix of (Win 2k8 R2/2012 R2/2016 servers).
- 3 x Read Only (Secondary) DNS servers
- 4 x Master DNS servers
The 4 x Master DNS severs are:
- AD integrated zones
- Dynamic Updates = Secure Only
- Aging and scavenging is setup and working
I want to reduce internet traffic so that only 1 or 2 DNS servers are configured with my ISP DNS servers as forwarders or root hints. Do I need to configure all the other DNS servers in the domain with the IPs of the 2 DNS servers I configure for External ISP DNS or root hints as Forwarders in order for them to resolve external sites?
DNS1 - confirgured for ISP DNS or root hints
DNS2 - confirgured for ISP DNS or root hints
DNS3 - Set DNS1 & DNS2 on the forwarders tab?
DNS4 - Set DNS1 & DNS2 on the forwarders tab?
DNS5 - Set DNS1 & DNS2 on the forwarders tab?
DNS6 - Set DNS1 & DNS2 on the forwarders tab?
DNS7 - Set DNS1 & DNS2 on the forwarders tab?
Any help would be appreciated.
