javascript - Getting client hostname in Node.js

Question

is it possible to get hostname in Node.js?

This is how I get client's IP:

var ip = request.header('x-forwarded-for');

So, how do I get client's hostname?

var hostname = request.header('???');

Thanks for reply!

You can use the 'dns' module to do a reverse dns lookup:

require('dns').reverse('12.12.12.12', function(err, domains) {
    if(err) {
        console.log(err.toString());
        return;
    }
    console.log(domains);
});

See: http://nodejs.org/docs/v0.3.1/api/all.html#dns.reverse
