Tool updating DNS data for dynamic IP addresses


Updates dynamic IP addresses typically obtained using DHCP with dynamic DNS services such as changeip.com, duckdns.org or no-ip.com. This makes it possible to access a machine with a fixed name like myhost.duckdns.org even if the ip address changes. It is a linux-centric, user-friendly and secure alternative to the ubiquitous ddclient(8)

ddupdate has a plugin structure with plugins for obtaining the actual address (typically hardware-dependent) and to update it (service dependent). It is distributed with systemd support to run at regular intervals and with NetworkManager templates to run when interfaces goes up or down.

The package sports a simple interactive setup script which should be suitable in most cases.
