Node.js - dnsPromises.resolve6() Method

Node.jsServer Side ProgrammingProgramming

The dnsPromises.resolve6() method uses the DNS protocol to resolve the IPv6 addresses (AAAA records) for the hostname. The promise is resolved with an array of IPv6 addresses.

Syntax

dns.resolve6(hostname, [options])

Parameters

  • hostname – This parameter takes input for hostname to be resolved.

  • options – It can have the following options −

    • ttl – It defines the Time-To-Live (TTL) for each record.

Example 1

Create a file with the name "resolve6.js" and copy the following code snippet. After creating the file, use the command "node resolve6.js" to run this code as shown in the example below −

// 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\node>> 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);
})();

Output

C:\home\node>> node resolve6.js
[ { address: '2404:6800:4002:81d::200e', ttl: 30 } ]
