Description Daneyon Hansen 2020-08-07 17:06:19 UTC 
Document URL: 
https://docs.openshift.com/container-platform/4.5/networking/dns-operator.html#nw-dns-forward_dns-operator

Section Number and Name: 
Using DNS forwarding

Describe the issue: 
See https://bugzilla.redhat.com/show_bug.cgi?id=1865806#c6

Suggestions for improvement:
Current:
You can use DNS forwarding to override the forwarding configuration identified in etc/resolv.conf on a per-zone basis by specifying which name server should be used for a given zone.

Proposed:
You can use DNS forwarding to override the forwarding configuration identified in etc/resolv.conf on a per-zone basis by specifying which name server should be used for a given zone. If the forwarded zone is a domain managed by openshift (e.g. the ingress domain), the upstream nameserver must be authoritative for the domain.
