Node for updating sub domains in Dreamhost DNS

npm install node-red-contrib-dreamhostdns-updater

DreamHost DNS Updater for Node Red

A Node to call Dreamhost DNS APIs based on DreamHost API Client for Node.js to update DNS entries of subdomain based on current ip address.

Usage

On each input message, the node resolves your current public IPv4 and IPv6 addresses using public-ip, then updates the DreamHost DNS records if they differ.

Optional msg.payload fields:

• payload.publicIPv4 — If set to a valid IPv4 string, it is used instead of auto-detection for the A record.
• payload.publicIPv6 — If set to a valid IPv6 string, it is used instead of auto-detection for the AAAA record.
• payload.ipLookupTimeout — Milliseconds for public IP lookup (default 10000). Ignored for addresses supplied manually above.

Requires Node.js 22.x (LTS; see package.json engines). For local development with nvm, run nvm use in this repo; .nvmrc pins 22.22.2.

Output provides the following information in msg.payload

• payload.error : Boolean value to inform if there was an error
• payload.errorMsg : If there was an error, the error Message, else empty string
• payload.updatedIPv4 : If IPv4 was updated
• payload.updatedIPv6 : If IPv6 was updated

Example Flow

The example flow triggers the Dreamhost node on a timer; public IPs are resolved inside the node (no separate IP discovery node required).
