native-dns 1:1 mapping of the upstream node.js dns module is broken

[mdebruijne]

Hi,

See below for scripts to reproduce the errors and the output when running these scripts. The only difference between these scripts is the usage of upstream node.js dns versus native-dns.

I think that the scripts and outputs are self-explanatory, but if more information is required then please let me know.

This is with node version 0.12 and native-dns version 0.7.0.

"use strict";

var dns = require("dns");
//var dns = require("native-dns");

var ip = "199.180.112.34";

dns.reverse(ip, function (err, hostnames) {
  if (err) {
    console.log(err);
  } else {
    console.log(hostnames);
  }
});

$ node dns.js
{ [Error: getHostByAddr ENOTFOUND 199.180.112.34]
  code: 'ENOTFOUND',
  errno: 'ENOTFOUND',
  syscall: 'getHostByAddr',
  hostname: '199.180.112.34' }
