Previously, if a piggyback source identified a piggybacked host by its IP address instead of its hostname, it was handled incorrectly in Checkmk:
- The host was not identified as a piggybacked host, meaning the relevant services would not be discovered.
- Downloading the agent output yielded empty data for such hosts
All affected lookups now also check the configured IPv4 and IPv6 addresses of the host, so piggyback data sent under either the hostname or any configured IP address is found correctly.
