https://www.speedguide.net/port.php?port=49204I've run a UDP port scan using nmap, I can see port 49204 ("unknown") listed - anyone have any idea what this might be?
Thanks!
Likely something special to your system, does not exist on my Pi5.Dynamic/Private : 49152 through 65535.
udp port 5353 is most likely MDNS:pi@raspberrypi5:~ $ time sudo nmap -sU -p1-65000 127.0.0.1

No idea what port 40722 does on my Pi5, keeps the same for multiple nmap runs:

"sudo netstat -lunp" does not tell anything for ports above 3433 on my Pi5.
