2 entries are registered on port 20014. It is a registered port (1024–49151) — IANA records an assignee, but nothing stops other software from listening here, which is why the number carries more than one entry.
DART Reporting Server typically functions as an endpoint for data collection, aggregation, and analytics within enterprise environments, enabling centralized reporting of operational or security events across an organization's infrastructure.
The registry says what 20014 is registered to. What is listening on it right now is decided by the host, and only the host can be asked. Each of these prints the process behind the socket.
linux
ss -ltnp | grep ':20014\b'
macos
lsof -nP -iTCP:20014 -sTCP:LISTEN
windows
netstat -ano | findstr :20014
On Linux and Windows the process name comes back with the socket; on macOS lsof needs sudo to name a process that isn't yours. Match what it prints against the 2 entries above.
A port number is not a service. Anything may listen on 20014 — what you actually met is decided by the host, not the registry. If a service is missing here, it belongs in the registry.
