We can verify this by enabling DNS debug logging where we see hundreds of megabytes of DNS traffic every hour on all of our DNS servers. We recently identified that a large portion of our network bandwidth is being utilized by DNS, specifically UDP traffic on port 53 between the different DNS servers.
