Overview

The No-IP.com Dynamic DNS Update Client (DUC) periodically checks the local IP address to see if it has changed. If the IP address has changed, the client notifies the No-IP.com DNS servers and updates the IP address corresponding to the user's No-IP/No-IP+ configured hostname(s).

A valid No-IP.com account is required.

The client communicates with the No-IP.com server over TCP on port 8245 (outgoing).
