DDNS Updater on Ubuntu 24.04

Overview

DDNS Updater is an open source dynamic DNS client. It checks what your current public IP address is on a schedule and, whenever that address changes, it calls your DNS provider and rewrites the A and AAAA records you have told it to look after, so a name you own always resolves to the machine you are running. It speaks to more than fifty providers, among them Cloudflare, DuckDNS, Namecheap, GoDaddy, Route 53, deSEC, Hetzner, Porkbun, DynV6 and No IP, plus a generic HTTP provider for anything else, and it can look after several domains and subdomains at once. A built in web interface lists every record it manages with the provider it belongs to, whether it is tracking IPv4 or IPv6, the result of the last update, the address currently published and the addresses that came before it, and a single click forces an immediate refresh.

Common uses

• Keep a domain pointing at a server or home connection that has a changing IP address
• Publish a stable hostname for remote access, VPN endpoints or self hosted services
• Manage dynamic DNS records for several domains and providers from one place
