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()
