@lhotari 
We have a scenario like we pulsar pods deployed in  Kubernetes namespace< 
pulsar> and client pods deployed in other namespace<tenant1> .
when the client tries to talk to pulsar proxy pods we provide the service url 
and pulsar url like https://pulsar-proxy. pulsar:8443 this internal will 
resolve to https://pulsar-proxy.pulsar.svc.cluster.local:8443 and this 
connection works and clients are able to communicate with pulsar server .

but there are additional search DNS happening in the client side for other 
entries in etc/resolve.conf which may not be correct . but this incorrect 
connections is tried in specific intervals again and again and logs in proxy 
logs .

As suggested i tried to give the trailing dot but the resolution will stop at 
https://pulsar-proxy.pulsar:8443 which will not work for cross namespace 
Kubernetes communication .
