ddclient 3.8.1-1ubuntu2 (arm64 binary) in ubuntu trusty

 This package provides a client to update dynamic IP addresses with
 several dynamic DNS service providers, such as DynDNS.com.
 .
 This makes it possible to use a fixed hostname (such as
 myhost.dyndns.org) to access a machine with a dynamic IP address.
 .
 This client supports both dynamic and (near) static services, as well as
 MX record and alternative name management. It caches the address, and
 only attempts the update when it has changed.
