// Passing a single dns to get values
dnsPromises.resolve6('tutorialspoint.com').then((response) => {
console.log("Resolved address is:", response);
})Output
C:\home

Example 2
// dns.resolve6() Demo Example
// Importing the dns module
const dns = require('dns');
const dnsPromises = dns.promises;
// Setting ttl as true
const options={
ttl:true,
};

// asynchronously
(async function() {
const records = await dnsPromises.resolve6('google.com', options);
