Technical Details

what runs on :6506

BoKS Admin Public Port is registered on port :6506 over tcp and udp to Magnus Nystrom. We don't have a technical write-up for it beyond the IANA registry entry.

In nmap's internet-wide scan data this port is never observed open, so if it's open on your network it's more likely a custom or misconfigured service than the registered one.
