Port 17220Audio Video Transport Protocol (AVTP)

Port 17220 is assigned to IEEE 1722 AVTP, a time-sensitive media transport normally carried directly over Ethernet.

Technical Details

what runs on :17220

The assignment associates TCP and UDP port 17220 with IEEE 1722 AVTP, but the standard AVTP data path is at the Ethernet layer, using EtherType 0x22F0—not TCP or UDP. AVTP frames carry time-sensitive media streams with fields such as stream identifiers and sequence numbers, and may include presentation timestamps. There is no TCP handshake or UDP port framing in that native Ethernet path; a TCP or UDP listener on 17220 should be treated as implementation-specific rather than assumed to be ordinary AVTP.

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

AVTP is generally used on managed local AVB/TSN networks, not exposed as an internet-facing service. Native AVTP does not provide encryption by default, and the port assignment alone does not identify what a TCP or UDP listener on 17220 does; investigate the process and implementation if one is present. Internet-wide scan data has not observed this port open.

Record

iana registry entry

port: :17220
service: Audio Video Transport Protocol (AVTP)
transport: TCPUDP
encryption: cleartext
assignment: iana registered
risk: 1/10safe
category: Network Services Media
usage: IANA assigns TCP and UDP port 17220 to IEEE 1722 AVTP, used in Audio Video Bridging and Time-Sensitive Networking environments. In practice, AVTP data is normally carried in Ethernet frames rather than sent to a TCP or UDP port, so an open 17220 socket may be implementation-specific.
