Cloudflare Ddns

This project is a Rust-based network utility and dynamic DNS client designed to monitor public IP addresses and automatically update Cloudflare DNS records and Web Application Firewall access lists. It identifies current IPv4 and IPv6 addresses using a combination of HTTP APIs and DNS-over-HTTPS providers.

The tool distinguishes itself by managing both domain records and WAF IP lists to maintain secure access for hosts with changing internet connections. It includes a DNS change preview mode to simulate updates without modifying live records and utilizes anycast range filtering to prevent incorrect record updates from provider address spaces.

The system handles scheduling via cron expressions or fixed intervals and implements jittered API request timing to avoid rate limiting. It covers broad capability areas including dual-stack network support, environment-based secret injection for authentication tokens, external status notifications, and heartbeat-based health monitoring.

Features

  • DNS Record Updaters - Automatically synchronizes current public IP addresses with Cloudflare DNS records.
  • Public IP Detectors - Identifies current public IPv4 and IPv6 addresses using HTTP APIs and DNS-over-HTTPS providers.
  • Dual-Stack Record Management - Processes and updates both IPv4 and IPv6 records simultaneously to maintain connectivity across different network stacks.
  • Dynamic DNS Mappings - Automatically refreshes DNS records when the public IP changes to ensure constant host connectivity.
