Java Integer.parseInt() Not Working for Large Numbers

Question

I have the following simple piece of code which is intended to detect that a given IPv4 address indeed only has numeric values (that is after the dots have been stripped):

import edu.gcc.processing.exceptions.net.IPAddressNumericException;

//Get the IP address
  String address = "239.255.255.255";

//Check to see if this is a number      
  try {
    String IPNumbers = address.replace(".", "");
    Integer.parseInt(IPNumbers);            
  } catch (NumberFormatException e) {
    System.out.print(e.getMessage());
  }

For some reason, the NumberFormatException is fired, and I get this error:

For input string: "239255255255"

Could someone please help me understand this? The parseInt() method works on smaller numbers, such as 127001.

Thank you for your time.

try using Long.parseLong(IPNumbers)
