Port 65506
In live entertainment systems, port 65506 is used by TPM2.net.
udp/65506
TPM2.net — TPM2.net data frames
A minimal LED matrix protocol from the ledstyles.de community: a start byte, a block type, a 16-bit frame size and raw pixel bytes, sent over UDP. It turns up whenever Jinx! or cheap ESP-based matrix hardware meets a real show and something has to feed it.
Check it from the command line
npx showstack port 65506
