Technical Details

what runs on :6486

The registry identifies this as the default secure IIOP domain for Sun Service Registry. IIOPS carries CORBA GIOP requests over IIOP protected by SSL/TLS: clients establish the TLS connection before exchanging CORBA requests, and CORBA object references direct clients to the endpoint. IIOP is normally connection-oriented and uses TCP; although IANA lists both TCP and UDP for this assignment, that does not establish that a UDP listener is present or commonly used.

security overview

TLS protects the transport when enabled and correctly configured, but it does not by itself control which CORBA objects or operations a client can invoke; that depends on the service's authentication and authorization configuration. Avoid exposing a legacy ORB endpoint directly to the internet, and restrict access to trusted clients. No internet-wide open observations were reported in the supplied scan data.
