Cita: A second-generation Linux client for dynamic DNS service
This is the No-IP.com Dynamic DNS update client.
When configured correctly, the client will check your IP address at a
given time interval checking to see if your IP has changed. If your
IP address has changed it will notify our dns servers and update the
IP corresponding to your No-IP/No-IP+ hostname.
