    Description

      In env with dynamically changing IP addresses, debugging issue with the logs with only IP address becomes a bit difficult at times.

      2023-02-08 23:26:50,112 WARN  [Socket Reader #1 for port 8485] ipc.Server - Incorrect RPC Header length from {IPV4}:36556 expected length: java.nio.HeapByteBuffer[pos=0 lim=4 cap=4] got length: java.nio.HeapByteBuffer[pos=0 lim=4 cap=4] 

      It would be better to log full hostname for the given IP address rather than only IP address.
