dns.Resolver

class Resolver

An independent resolver for DNS requests.

Creating a new resolver uses the default server settings. Setting the servers used for a resolver using resolver.setServers() does not affect other resolvers:

import { Resolver } from 'node:dns';
const resolver = new Resolver();
resolver.setServers(['4.4.4.4']);

// This request will use the server at 4.4.4.4, independent of global settings.
resolver.resolve4('example.org', (err, addresses) => {
  // ...
});

The following methods from the node:dns module are available:

  • resolver.getServers()
  • resolver.resolve()
  • resolver.resolve4()
  • resolver.resolve6()
  • resolver.resolveAny()
  • resolver.resolveCaa()
  • resolver.resolveCname()
  • resolver.resolveMx()
  • resolver.resolveNaptr()
  • resolver.resolveNs()
  • resolver.resolvePtr()
  • resolver.resolveSoa()
  • resolver.resolveSrv()
  • resolver.resolveTxt()
  • resolver.reverse()
  • resolver.setServers()
