DNS issues resolving after upgrade to Ventura

After upgrade to Ventura I found that I can no longer use the local host name (e.g. pi, pi4main) to access the equipent in LAN.

Symptom

The following command works:

nslookup <LOCAL_HOSTNAME>
hosts <LOCAL_HOSTNAME>

Following command failed:

ping <LOCAL_HOSTNAME>
ssh <LOCAL_HOSTNAME>

Solution

I resolved the issue via suggestions from https://github.com/michthom/AlwaysAppendSearchDomains By running following command:

sudo defaults write /Library/Preferences/com.apple.mDNSResponder.plist AlwaysAppendSearchDomains -bool YES
