dns

You can use node:dns ↗ for name resolution via DNS over HTTPS using Cloudflare DNS ↗ at 1.1.1.1.

import dns from "node:dns";

let response = await dns.promises.resolve4("cloudflare.com", "NS");

import dns from 'node:dns';

let response = await dns.promises.resolve4('cloudflare.com', 'NS');

All node:dns functions are available, except lookup, lookupService, and resolve which throw "Not implemented" errors when called.

The full node:dns API is documented in the Node.js documentation for node:dns ↗.
