The dns.getServers() method is an inbuilt application programming interface of the dns module which is used to get IP addresses of the current server.
Syntax: 
 

dns.getServers()

Below examples illustrate the use of dns.getServers() method in Node.js:
Example 1: 
 

// Node.js program to demonstrate the   
// dns.resolveSoa() method

// Accessing dns module
const dns = require('dns');

// Reading IP address of the current host
// and printing it to the console
console.log(dns.getServers());

Output: 
 

[ '2402:3a80:1103:a055::34', '192.168.43.1' ]

Example 2: 
 

// Node.js program to demonstrate the   
// dns.resolveSoa() method

// Accessing dns module
const dns = require('dns');

// Reading IP address of the current host
// and printing it to the console
res = dns.getServers();

res.forEach(element => { 
    console.log(element); 
});

Output: 
 

72.28.94.156
2306:2470:3160::8888
72.28.94.156:1053
[2306:2470:3160::8888]:1053

Note: The above program will compile and run by using the node index.js command.
