Function to Check IpAddress is within a Specified Range

The code snippet is used to check the IpAddress given is within a specified range. It will set the inRange boolean to true if IpAddress is within that range.

/**
  * @param args
  * @throws UnknownHostException 
  */
 public static void main(String[] args){
  // TODO Auto-generated method stub
  
  //Pass the IpAdress to check whether it is in the Specified Range
  String ipAddress = "";
  //IpAddress Ranges are to be Specified here.
  String ipAddressRange = "";
  boolean inRange = false;
  if (!ipAddressRange.isEmpty()){
   String[] addressRanges = ipAddressRange.split(",");
   for (String ipAddr:addressRanges){
    String[] ipAddrLowHigh = ipAddr.split("-");
    try {
     long ipAddrLower = ipToLong(InetAddress.getByName(ipAddrLowHigh[0]));         
     long ipAddrHigher = ipToLong(InetAddress.getByName(ipAddrLowHigh[1]));         
     long ipAddrToTest = ipToLong(InetAddress.getByName(ipAddress));  
     inRange = ipAddrToTest >= ipAddrLower && ipAddrToTest <= ipAddrHigher;
     System.out.println("True = If Ipaddress is within the range:::::"+inRange);
     if (inRange){
      break;
     }
    } catch (UnknownHostException ex){
     System.out.println("UnknownHostException Occurred in IFAUtils.isIpAddressRange:::"+ex.getMessage());
     ex.printStackTrace();
    }
   } 
  } 
 }
