Technical Details

what runs on :96

DIXIE defines client requests and server responses for directory operations and was assigned port 96 for both TCP and UDP. It is a separate, older protocol from LDAP, with no modern expectation of TLS encryption or contemporary LDAP framing; deployments should be treated as implementation-specific legacy systems.

Security Information

exposure of :96

risk score

1/ 10safe

routine exposure. this port is rarely the way in on its own — keep it patched and logged and move on.

network services averages 3.7 across 669 ports — this one sits 2.7 below.

in transit

reachable over

tcp · udp

udp is connectionless — source addresses are trivially spoofed and it is a reflection favourite

security overview

DIXIE traffic should be presumed unencrypted unless protected externally, so directory queries or authentication material may be exposed to network observers. Because the protocol is obsolete and rarely deployed, internet exposure is generally unnecessary; restrict it to trusted networks and identify the implementation before allowing access.
