// dns.resolve6() Demo Example // Importing the dns module const dns = require('dns'); const dnsPromises = dns.promises; // Passing a single dns to get values dnsPromises.resolve6('tutorialspoint.com').then((response) => { console.log("Resolved address is:", response); })
Output
C:\home
ode>> node resolve6.js Resolved address is: undefined
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, }; // Calling dnsPromises.resolve6() method // asynchronously (async function() { const records = await dnsPromises.resolve6('google.com', options); // Printing records console.log(records); })();
