Ionos DDNS update script

This is a simple set of scripts that allows the user to obtain the internal ID used by Ionos to identify DNS zones and domain records registered to their account, and then automatically update one or more records using a script set to run with crontab or a similar scheduler.

Setup

The scripts rely on a single .env file in the same directory as the script. This .env file should have the following variables:

API_KEY=[your key]
API_KEY_PUBLIC=[your public prefix]
ZONE_ID=[your zone ID]
DOMAIN_ID=[your domain ID]
LOGGING=[true or false]

ZONE_ID and DOMAIN_ID can be obtained using the get_record_ids.py script. You can obtain an API key from the Ionos developer portal.

Automating DNS record updates

The script ionos_ddns_update.py updates the DNS record DOMAIN_ID, which itself is located within DNS zone ZONE_ID. This script can be run at any time - I recommend automating it to run at the desired interval with a tool like crontab.

The LOGGING variable in the environment file enables or disables logging in the ionos_ddns_update.py script. Set to TRUE or FALSE.

An example crontab entry looks like this:

0 * * * * cd /home/jacob/ionos_ddns_script && /usr/bin/python3 /home/jacob/ionos_ddns_script/ionos_ddns_update.py

Note that I cd into the working directory where I want the log file to be located before running the script.
