A Cloudflare Worker script that enables UniFi devices (e.g., UDM-Pro, USG) to dynamically update DNS A/AAAA records on Cloudflare.

UniFi devices do not natively support Cloudflare as a DDNS provider. This script bridges that gap, allowing your UniFi device to keep your DNS records updated with your public IP address.
