### Question:
IpUtils { public boolean isIpAddress(String ip) { return isDecimalIpAddress(ip) || isBinaryIpAddress(ip) || isOctalEncodedIpAddress(ip) || isHexEncodedIpAddress(ip) || isNumericIpAddress(ip); }  boolean isIpAddress(String ip); boolean isDecimalIpAddress(String ip); boolean isBinaryIpAddress(String ip); boolean isOctalEncodedIpAddress(String ip); boolean isHexEncodedIpAddress(String ip); boolean isNumericIpAddress(String ip); InetAddress toInetAddress(String ip);  }### Answer:
@Test public void testIsIpAddress() { Assert.assertTrue(ipUtils.isIpAddress(ipDec)); Assert.assertTrue(ipUtils.isIpAddress(ipHex)); Assert.assertTrue(ipUtils.isIpAddress(ipOct)); Assert.assertTrue(ipUtils.isIpAddress(ipBin)); Assert.assertTrue(ipUtils.isIpAddress(ipNum)); }
