I'm running this script every hour through cron as such:
0 */1 * * * /usr/bin/node /path/to/node-ip-change-dns-updater/index.js >> /path/to/logs/node-ip-change-dns-updater.log
- Checks the external IP of your connection.
- Gets DNS entries from chosen domain (config.js) from TransIP.
- Verifies this IP with the IP address of the DNS entry of your liking (config.js).
- Updates DNS entries at TransIP if the external IP address differs from the DNS entry.
