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.

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

Usage:

Clone this repo
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 .
```
Copy config.example.yaml as config.yaml into the same directory the script is located and configure your settings.
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.
