Dynamic IP Updater for name.com DNS

Minimal script for checking a machine's external IP and updating its DNS when the IP address changes using the name.com APIs.

Features

• Simple yaml driven config
• Uses name.com's publicly documented APIs for managing DNS
• Avoids making excessive calls to name.com's APIs by storing the last known public IP and only trying to make updates if there are changes.
• Low-noise default logging (for info level & above)
• Optionally sends email updates when an IP changes
• Optionally sends email updates when an error happens
• Avoids repeat error emails if the script rapidly fails during repeated runs.

Dependencies & Usage

Requires python and pip to be installed on the machine running the script.

Usage:

1. Clone this repo
2. From within the repository's root folder, setup a python venv to install dependencies with the following commands:

   python3 -m venv env
   source env/bin/activate
   pip install .

3. Copy config.example.yaml as config.yaml into the same directory the script is located and configure your settings.
4. Run the script. Set it as a chron job or Systemd timer to update as often as you'd like. Systemd unit files are included in this repository and require setting the DYNDNS_WORKING_DIR environment variable so the systemd service can reference it.
