Why is my RHEL server communicating to root DNS directly and not routed through internal DNS
Issue
- RHEL server communicating to root DNS directly and not routed through internal DNS.
- In logs could only find DNSSEC validation-related messages in servers at the reported time.
[root@xyz ~]# cat /var/log/messages| grep 00:00
