Code :

var scanner = new require('netscan')(); //may eventually take in options

// this would scan ip in the range of 192.168.1.[3-163]
// with ports of [80, 90, 443, 1337]
// and accept response codes of [200, 201, 202, 400, 401, 402, 403]

scanner.scan({

    protocol : ['http'],

    octet0: [192],
    octet1: [168],
    octet2: [1],
    octet3: [{min: 3, max: 163}], //range of 7 to 10 inclusive

    ports: [80, 90, 443, 1337],

    codes: [200, 201, 202, 400, 401, 402, 403], //only count it if a 200 comes back,

    errors : [], //like 'ETIMEDOUT'

    paths: '/' || [string], // optional to have it hit a specific endpoint

    headers: {}, // include the following headers in all request so you can do auth or something,

    timeout: 10000, //10 seconds timeout)

    ignoreResponse : true //tells it to not return the body as part of the results


}, function callback(results){

  /*
    results will contain response
    {
      uri : string,
      code : httpResponseCode ie. [200],
      body : httpResponseBody
    }
