### Question:
ValidateIPaddress { public static boolean isIPv6(String ipAddress) { if (ipAddress == null || ipAddress.isEmpty()) { return false; } Matcher ipv6Matcher = IP_V6_PATTERN.matcher(ipAddress); return ipv6Matcher.find(); } private  ValidateIPaddress(); static boolean isIPv4(String ipAddress); static boolean isIPv6(String ipAddress); static boolean isValidIP(String ipAddress);  }### Answer:
@Test(dataProvider = "addresses") public void testWildcardInProtocol(boolean expected, String address) { boolean result = ValidateIPaddress.isIPv6(address); assertEquals(result, expected); }
