DDNS6 - One dynamic DNS client for multiple hosts

DDNS6 is a dynamic DNS client for updating dynamic DNS entries for multiple hosts.

Note: The project is currently in an early stage of development. Don't use in production!

DDNS6 supports updating dynamic DNS entries for accounts on many dynamic DNS services. It has the following great advantages:

• Built for IPv4/IPv6 dual-stack.
• One instance for multiple hosts. DDNS6 supports configuring address prefix and suffix separately and combining them together to batch update dynamic DNS entries for multiple hosts.
• Cross-platform. Running on Linux, OpenWrt/LEDE, EdgeOS/Vyatta, Windows, and macOS.
• Great performance with low resource cost by being native and using asynchronous I/O.

Getting Started

Build

$ cargo build --release

The resulting binary is at ./target/release/ddns6.

Configuration

NOTE: As of this writing, only he.net provider is supported.

This is a simple example: The domain name 1.example.com is hosted on https://dns.he.net. The IPv4 address is obtained from web, and IPv6 address is a combination of prefix from local interface br0 and suffix of static value ::1.

# config/ddns6.toml
[[entries]]
hostname="1.example.com"
username="1.example.com"
password="your-password"
provider="he.net"
ipv4={web="_"}
ipv6=[{addr={dev="br0"}, len=64}, "::1"]

Run

./ddns6

Current version of DDNS6 updates the DNS records for domain names every 5 minutes.
