This is a simple dynamic DNS updater for the
[Gandi](https://www.gandi.net) registrar. It uses their [LiveDNS REST API](http://doc.livedns.gandi.net/) to update the zone file for a subdomain of a domain to point at the external IPv4 address of the computer it has been run from.
~~It has been developed on Debian 8 Jessie and tested on Debian 9 Stretch GNU/Linux using Python 2.7.~~

### Run with Docker
Use the docker file to build the image. With docker, the script will run every 3600 seconds. (This value can be changed in the Dockerfile.
### Limitations
The XML-RPC API has a limit of 30 requests per 2 seconds, so i guess it's safe to update 25 subdomains at once with the REST API.
### Upcoming Features
* ~~command line Argument for verbose mode~~ Aditional verbosity implemented.
