DynDNS on Ubiquiti EdgeRouter: step-by-step setup
The Ubiquiti EdgeRouter (EdgeOS) ships with a DynDNS2 client via ddclient that can target any custom server. With DNS Beacon your network stays reachable under a permanent hostname even when your WAN IP changes. Here's how to configure it via the CLI.
Step by step
- Open the admin interface of your Ubiquiti EdgeRouter and go to CLI (configure) — or GUI: Services → DNS → Dynamic DNS.
- Enter the values below. Your username is your account email, your password is an API key from the dashboard.
- Save the settings. Your hostname now updates automatically whenever your IP changes — usually within a minute.

EdgeOS uses ddclient. In the CLI: `set service dns dynamic interface eth0 service custom-dnsbeacon protocol dyndns2`, then `server <API host>`, `host-name <hostname>`, `login <email>`, `password <API key>` — then `commit; save`. Replace eth0 with your WAN interface.
Need a free hostname first?
