By this I mean, I have a powerdns server running in my cluster, I would like Kubernetes to add/update dns entries in my dns server to reflect all services or any domains that would be used within the cluster, this is to fix a current issue I am having, and for general control and centralization purposes.

Your k3s/calico networking is likely screwed. Try creating a new cluster with flannel instead.

Well I switched to cilium, same issue, and the reason I started using a CNI earlier than I intended was because flannel didn't work.

This issue might seem complex but could you tell me some debugging stuff and logs to try to maybe get to the source of the issue or atleast provide a way to reproduce my issue (so I could maybe file a bug report)

It might be a simple issue like ip forwarding not being enabled, or host-level iptables configuration, or perhaps weird and wonderful routing (eg. wireguard or other VPNs).
