A terrible solution for finding network gateway

lol.js

//
// Since the code to actually figure this out doesn't exist in node yet
//
// see: https://groups.google.com/forum/?fromgroups#!topic/nodejs-dev/QbcnxS0_yyg
//
var guessGateway = function () {
  var network = os.networkInterfaces(),
      guess = '10.0.0.1';

  Object.keys(network).forEach(function(interfaces){
    network[interfaces].forEach(function(interface){
      if(!interface.internal && interface.family === "IPv4") {
        guess = interface.address.split('.');
        guess[guess.length -1] = "1";
        guess = guess.join('.');
      }
    });
  })

  return guess;
};

What's the best way nowadays to find the gateway's IP Address in Node?
