What does socket.io bind to?

Question

Node.js

Hello! There is a local project on port 3000, on which sockets exchange client-server data. Now such a moment, I open the address of the project in Google Chrome, the data has been transferred, everything is fine. I open it in Safari, the same effect, the same data was transferred. I open from an iPhone at the local address 192.168.1.*:3000 there is no data. And this result seems to suit me, because this is authorization data, and in theory they should be assigned to the browser, but I have a feeling that they are assigned to the ip-shnik, and not to the browser. How should it work correctly?
Here is the server and client source:

var app = angular.module('selfMade');
app.controller('MainController', ['$rootScope', '$scope', 'socket', function ($rootScope, $scope,  socket) {
    socket.on('auth',function(data){
        $rootScope.auth = data;
    });
  }
}]);

module.exports = function (app) {
    var io = app.get('socket');
    passport.use('vk', new vk(vk_conf, function (accessToken, refreshToken, params, profile, done) {
            io.on('connection', function(socket) {
                socket.emit('auth', profile);
            });
    }));
}

You are talking about the session, it seems that the session is assigned to the domain, in this case your domain is ip.
