How to do whitelist of IP's in nodejs?

Below is my app.js file.. i need to block every other ip address from accessing my site except one or two ip's provided by me.i have tried many modules but nothing suits.

var express = require('express')
var AccessControl = require('express-ip-access-control');
var app = express()

app.get('/', function (req, res) {
  res.send('Hello World!')
})

var middleware = AccessControl(options);
 app.use(AccessControl(options));

var options = {
    mode: 'deny',
    denys: ['**8.1**.1.**'],
    allows: [],
    forceConnectionAddress: false,
    log: function(clientIp, access) {
        console.log(clientIp + (access ? ' accessed.' : ' denied.'));
    },

    statusCode: 401,
    redirectTo: '',
    message: 'Unauthorized'
};

app.listen(3000, function () {
  console.log(' app listening on port 3000!')
})

on running and accessing my site from my above code i am getting the console message as

::ffff:127.0.0.1 accessed.
::ffff:127.0.0.1 accessed.
::ffff:127.0.0.1 accessed.
::ffff:127.0.0.1 accessed.
