Technical Details
what runs on :4160Jini discovery uses UDP multicast for lookup-service discovery, including client requests and registrar announcements, with TCP used for subsequent unicast discovery exchanges where configured. The protocol is Java/Jini-specific and is normally limited to a local network; multicast discovery commonly uses the 4160 service port, while lookup services may also advertise separate unicast endpoints. Traffic is not encrypted by default.

security overview
Jini discovery can expose the presence and locators of lookup services and may allow unwanted clients to probe discovery endpoints. It should generally be restricted to trusted local networks with filtering at network boundaries; internet exposure is unusual and provides little legitimate benefit.
