Here is a small list of Bad IPv4 addresses that java_net.URL class is not catching. I found these while testing the URL.equals() method
A MalformedURLException should be thrown if address is bad.

List:
"129.300.455.976",
       "129.144.126",
       "129.144.126.",
       "129.144.126.29.",
       "129.144.126.29.10",
       "129.144.-16.10",
       "129.0x90.126.29"


Test Program:

import java.net.*;

public class bug {
  public static void main(String[] args) {
    
    String bad_addr4[] = {
      "129.300.455.976",
      "129.144.126",
      "129.144.126.",
      "129.144.126.29.",
      "129.144.126.29.10",
      "129.144.-16.10",
      "129.0x90.126.29" };
    
    String s[] = bad_addr4;
    
    
      int i = 0;
      while ( i < s.length ) {
try {
URL url = new URL("http://"+s[i]);
System.err.println("Test FAILed:"
+ " URL constructor did not throw exception.");
} catch (MalformedURLException e) {
System.out.println("Test PASSed: URL constructor threw exception.");
System.out.println(e.getMessage());
}
i++;
      }
  }
}
