function resolve

Usage in Deno

import { resolve } from "node:dns/promises";
resolve(hostname: string): Promise<string[]>

Uses the DNS protocol to resolve a host name (e.g. 'nodejs.org') into an array of the resource records. When successful, the Promise is resolved with an array of resource records. The type and structure of individual results vary based on rrtype:

<omitted>

On error, the Promise is rejected with an Error object, where err.code is one of the DNS error codes.
