Technical Details

what runs on :9011

D-STAR Routing uses UDP port 9011 for D-STAR digital voice and data routing between participating amateur-radio gateway infrastructure and the QuadNet2 network. It is a specialized gateway-to-network service, not a conventional interactive client protocol; the IANA registration does not document a universal handshake, packet framing, or companion-port requirements.

security overview

D-STAR traffic is not encrypted by default, so voice and data exchanged through this service should be treated as observable on the network. Internet exposure should generally be restricted to the gateway peers and routing infrastructure that require it; do not expose it broadly unless the gateway software and network design require inbound UDP access. The port is uncommon and there are no widely known general-purpose exploits associated with it.
