1. To have a list of all IPs and then look for the resultant IP list
2. Use Nested Loop

IP Bytes -> Bits -> Int32
From: 10.0.10.10 -> 00001010 00000000 00001010 00001010 -> 167774730
To: 10.1.45.1 -> 00001010 00000001 00101101 00000001 -> 167849217
Start count from From to To and just check the unwanted Bytes witch is 11111111 and 00000000

var startIp = 0x0A000001,
    endIp = 0x0A000F05;

    var  temp, list = [],str;
    for(var i=startIp ; i <= endIp ; i++){
             temp = (i).toString(16);
             str ='';
             if(temp.length == 7){
                 temp = "0"+temp;
             }

             for(var k=temp.length-1; k  >= 0 ; k-=2){

                str = parseInt(temp[k-1] + "" + temp[k], 16) +"." + str ;

             }
             document.write(temp + " " + str+ "<br>");
             list.push(str.substring(0, str.length-1));
    }
