Node.js dns.getServers() Method Last Updated : 28 Apr, 2025 Comments Improve Suggest changes Like Article Like Report 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() Parameters: This method does not accept any parameters.Return: This method returns an array of IP addresses in RFC 5952 format as configured in DNS resolution for the current host. A string will be attached as the port number if a custom port is being used.Below examples illustrate the use of dns.getServers() method in Node.js:Example 1: javascript // 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: javascript // 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.Reference: https://nodejs.org/api/dns.html#dns_dns_getservers Comment More infoAdvertise with us Next Article Node.js dns.lookup() Method G gekcho Follow Improve Article Tags : Web Technologies Node.js Node.js-dns-module Similar Reads Node.js dns.getServers() Method 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:Â Â dns.getServers() Parameters: This method does not accept any parameters.Return: This method returns an array of IP addresses in RFC 5952 for 1 min read Node.js dns.lookup() Method The dns.lookup() method is an inbuilt application programming interface of the dns module which is used to resolve IP addresses of the specified hostname for given parameters into the first found A (IPv4) or AAAA (IPv6) record.
