resolve

function resolve

Usage

import { resolve } from "node:dns";


        resolve(hostname: string, callback: (err: ErrnoException | null, addresses: string[]) => void): void

Uses the DNS protocol to resolve a host name (e.g. 'nodejs.org') into an array of the resource records. The callback function has arguments (err, records). When successful, records will be an array of resource records. The type and structure of individual results varies based on rrtype:


        resolve(hostname: string, rrtype: "A", callback: (err: ErrnoException | null, addresses: string[]) => void): void


        resolve(hostname: string, rrtype: "AAAA", callback: (err: ErrnoException | null, addresses: string[]) => void): void


        resolve(hostname: string, rrtype: "ANY", callback: (err: ErrnoException | null, addresses: AnyRecord[]) => void): void


        resolve(hostname: string, rrtype: "CNAME", callback: (err: ErrnoException | null, addresses: string[]) => void): void


        resolve(hostname: string, rrtype: "MX", callback: (err: ErrnoException | null, addresses: MxRecord[]) => void): void


        resolve(hostname: string, rrtype: "NAPTR", callback: (err: ErrnoException | null, addresses: NaptrRecord[]) => void): void


        resolve(hostname: string, rrtype: "NS", callback: (err: ErrnoException | null, addresses: string[]) => void): void


        resolve(hostname: string, rrtype: "PTR", callback: (err: ErrnoException | null, addresses: string[]) => void): void


        resolve(hostname: string, rrtype: "SOA", callback: (err: ErrnoException | null, addresses: SoaRecord) => void): void


        resolve(hostname: string, rrtype: "SRV", callback: (err: ErrnoException | null, addresses: SrvRecord[]) => void): void


        resolve(hostname: string, rrtype: "TXT", callback: (err: ErrnoException | null, addresses: string[][]) => void): void


        resolve(hostname: string, rrtype: string, callback: (err: ErrnoException | null, addresses:  | string[]
 | MxRecord[]
 | NaptrRecord[]
 | SoaRecord
 | SrvRecord[]
 | string[][]
 | AnyRecord[]) => void): void

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