Technical Details

what runs on :716

PANA is defined by RFC 5191 and transports Extensible Authentication Protocol (EAP) messages over UDP. A PaC and PAA exchange PANA discovery, authentication, binding, and termination messages; the protocol includes message identifiers, retransmission handling, and attribute-value pairs inside a PANA header. The assigned service uses UDP port 716; PANA is distinct from link-layer EAPOL/802.1X and does not itself provide general application-layer encryption.

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

security overview

PANA should normally be reachable only within the access network or other tightly controlled authentication domain, not broadly from the public Internet. PANA traffic is not encrypted by default, so confidentiality and much of the authentication protection depend on the negotiated EAP method and any subsequently installed network-layer protection; exposed implementations may also be subjected to authentication probing or denial-of-service traffic.

port: :716
service: PANA (Protocol for Carrying Authentication for Network Access)
transport: UDP
encryption: cleartext
assignment: iana registered
risk: 2/10safe
category: Security Network Services
usage: UDP 716 carries PANA authentication exchanges between a PANA Client (PaC) and a PANA Authentication Agent (PAA). It is used in access networks to authenticate a host before granting network access, rather than as a general-purpose VPN or remote-access service.
