Technical Details

what runs on :5569

IANA assigns UDP/5569 to PLASA E1.33 RDM messages. RDMnet carries Remote Device Management commands between lighting controllers, brokers, and networked devices; its typical data connections use TCP and ACN packet framing, rather than a general-purpose UDP request/response protocol. UDP has no connection handshake, and the assignment alone does not establish what framing or behavior a UDP listener on this port implements. If you find UDP/5569 open, verify the device and traffic instead of assuming it is a standard RDMnet data connection.

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

security overview

RDMnet can carry commands that affect lighting equipment, and traffic is not encrypted by default. Keep lighting-control networks segmented and do not expose a suspected RDMnet service directly to the internet; an unexpected UDP listener should be identified before allowing access.

Record

iana registry entry

port: :5569
service: RDMnet (PLASA E1.33)
transport: UDP
encryption: cleartext
assignment: iana registered
risk: 2/10safe
category: Network Services
usage: The assignment is for RDMnet, used in professional lighting systems to manage and control networked devices such as lighting fixtures. RDMnet data connections are commonly described as using TCP, so a UDP listener on 5569 is not necessarily a typical RDMnet endpoint.
