Как получить значения ip адресов в массив - JavaScript

//get the IP addresses associated with an account 
function getIPs(callback){ 
    var ip_dups = {}; 
  
    //compatibility for firefox and chrome 
    var RTCPeerConnection = window.RTCPeerConnection 
        || window.mozRTCPeerConnection 
        || window.webkitRTCPeerConnection; 
    var mediaConstraints = { 
        optional: [{RtpDataChannels: true}] 
    }; 
  
    //firefox already has a default stun server in about:config 
    //    media.peerconnection.default_iceservers = 
    //    [{"url": "stun:stun.services.mozilla.com"}] 
    var servers = undefined; 
  
    //add same stun server for chrome 
    if(window.webkitRTCPeerConnection) 
        servers = {iceServers: [{urls: "stun:stun.services.mozilla.com"}]}; 
  
    //construct a new RTCPeerConnection 
    var pc = new RTCPeerConnection(servers, mediaConstraints); 
  
    //listen for candidate events 
    pc.onicecandidate = function(ice){ 
  
        //skip non-candidate events 
        if(ice.candidate){ 
  
            //match just the IP address 
            var ip_regex = /([0-9]{1,3}(\.[0-9]{1,3}){3})/ 
            var ip_addr = ip_regex.exec(ice.candidate.candidate)[1]; 
  
            //remove duplicates 
            if(ip_dups[ip_addr] === undefined) 
                callback(ip_addr); 
  
            ip_dups[ip_addr] = true; 
        } 
    }; 
  
    //create a bogus data channel 
    pc.createDataChannel(""); 
  
    //create an offer sdp 
    pc.createOffer(function(result){ 
  
        //trigger the stun server request 
        pc.setLocalDescription(result, function(){}, function(){}); 
  
    }, function(){}); 
} 
  
//Test: Print the IP addresses into the console 
getIPs(function(ip){console.log(ip);});
