Technical Details

what runs on :3716

The assignment identifies the SMS Client-Initiated Request (CIR) channel of Wireless Village CSP, the client-server protocol family for mobile instant messaging and presence. IANA lists both TCP and UDP for port 3716; the service name alone does not establish a generic SMS protocol or reveal the exact framing or handshake of a particular implementation. A matching WV CSP implementation would be needed for the port to have this meaning.

security overview

This is a legacy, specialized service rather than a port that should normally be exposed as a public SMS endpoint. The assignment does not establish that traffic is encrypted or authenticated, so do not assume either; if a matching implementation is found, restrict access to trusted service components and check its own security documentation.
