Port 6454
In live entertainment systems, port 6454 is used by Art-Net.
udp/6454
Art-Net — All Art-Net traffic (ArtDmx, ArtPoll, ArtPollReply, ArtSync, ...)
Artistic Licence's royalty-free protocol for carrying DMX512 over UDP/IP. It predates sACN, is implemented by almost every lighting product ever made, and is still the default lingua franca when two unfamiliar devices need to talk.
Check it from the command line
npx showstack port 6454
