Port 10111NMEA OneNet

UDP multicast messaging for NMEA OneNet marine electronics networks.

Technical Details

what runs on :10111

NMEA OneNet multicast messaging uses UDP on port 10111. UDP has no connection handshake or built-in retransmission, so a receiver listens for datagrams rather than accepting a persistent client session. The exact message format and multicast-group behavior are defined by the NMEA OneNet specification; the port assignment alone does not establish those details.

routine exposure. this port is rarely the way in on its own — keep it patched and logged and move on.

udp is connectionless — source addresses are trivially spoofed and it is a reflection favourite

security overview

This service is intended for marine-network messaging, not general internet exposure. UDP itself provides no transport encryption or session authentication, so restrict access to the intended vessel network and apply any protections required by the OneNet implementation. An exposed listener may receive unsolicited datagrams; the assignment is not commonly observed open in internet-wide scans.
