IP-addresses stored as int results in overflow?

Question

I\'m writing a chat-server in node.js, and I want to store connected users IP-addresses in a mysql database as (unsigned) integers. I have written a javascript method to convert

Answer 1

var aaa = Number("0b"+ "192.168.2.44".split(".").map(
  function(dec){
    return ("00000000" + Number(dec).toString(2)).slice(-8); 
  }).join(""));

aaa.toString(2).match(/.{1,8}/g).map(
  function(bin){
    return Number("0b"+bin); 
  }).join(".");
