Node.js dnsPromises.resolve6() Method Last Updated : 13 Oct, 2021 Summarize Comments Improve Suggest changes Share Like Article Like Report The dnsPromises.resolve6() method is an inbuilt application programming interface of the promises of dns module which is used to resolve IPv6 address ('AAAA' record) for the specified hostname using DNS protocol. Syntax: dnsPromises.resolve6( hostname, options ) Parameters: This method has two parameters as mentioned above and described below: hostname: This parameter specifies a string which denotes the hostname to be resolved. options: It is in the form of an object. ttl: It is a Boolean parameter, specifies whether the Time-To-Live value (TTL) for each record to be retrieved or not. If set to true, TTL for each record is retrieved (in seconds). Return Value: This method returns error, records. Below examples illustrate the use of dnsPromises.resolve6() method in Node.js: Example 1: javascript // Node.js program to demonstrate the // dnsPromises.resolve6() method // Accessing promises object from dns module const dns = require('dns'); const dnsPromises = dns.promises; // Calling dnsPromises.resolve6() method dnsPromises.resolve6('geeksforgeeks.org').then((res) => { console.log(res); }); // Calling dnsPromises.resolve6() method // asynchronously (async function() { // Records from resolve6 function const records = await dnsPromises.resolve6('geeksforgeeks.org'); // Printing records console.log("from async: "); console.log(records); })(); Output: from async: [ 'fd00:0:13:13::22da:3e74' ] [ 'fd00:0:13:13::22da:3e74' ] Example 2: javascript // Node.js program to demonstrate the // dnsPromises.resolve6() method // Accessing promises object from dns module const dns = require('dns'); const dnsPromises = dns.promises; // Setting options for dnsPromises.resolve6() method const options={ ttl:true, }; // Calling dnsPromises.resolve6() method // asynchronously (async function() { // Records from resolve6 function const records = await dnsPromises.resolve6( 'geeksforgeeks.org', options); // Printing records console.log("from async: "); console.log(records); })(); Output: from async: [ { address: 'fd00:0:13:13::22da:3e74', ttl: 30 } ] Note: The above program will compile and run by using the node index.js command.
