javascript - Prevent other people from emitting socket info -

i have node socket server running on same vps website is. there way can prevent other "websites" or other node projects connecting socket server , emitting data?

my website , node project have same ip address.

for example: (client side html)

<script>   var socket = io.connect('localhost') //localhost example   socket.on('example', function(data) {       console.log(data) ;   });   socket.emit('sendtoserver', 'hello world'); </script> 

i want code right here usable website (or ip)

edit: if there isnt within socket.io, there way can authenticate socket server make ip can emit things

if you're concerned it, should consider allowing authenticated users. otherwise trying ban explicit ip addresses , maintaining list isn't feasible.
