Can any one help me in getting clients machine-name/host-name for my website authentication.which is running internally in my pany domain. I tried the below code but got server host-name instead of client.

NodeJS DNS Reverse Lookup will do the trick. It is the only way. Check this link for more information :)

https://nodejs/api/dns.html#dns_dns_reverse_ip_callback

Try this below code

require('dns').reverse(req.connection.remoteAddress, function(err, domains) {
    console.log(domains);
});

To get ip Address of the client system or of any system you can do this.

Change req to whatever nomenclatural you are using

var ip = (req.headers["X-Forwarded-For"] || req.headers["x-forwarded-for"] || '').split(',')[0] || req.connection.remoteAddress;
console.log("ip address is:- " + ip);

To get the host name of the client system or of any system you can do this

const os = require('os');
var hostname = os.hostname(); 
console.log("Hostname is:- " + hostname);

This will work on both js and nodejs

function getClientAddress(req) {
  return req.headers['x-forwarded-for'] || req.connection.remoteAddress;
}

This will work !!

So, how do I get client's hostname?

  request.headers.host

hope this also works for you.
