### Question:
NetUtils { public static String getLogHost() { InetAddress address = LOCAL_ADDRESS; return address == null ? LOCALHOST : address.getHostAddress(); }  static int getRandomPort(); static int getAvailablePort(); static int getAvailablePort(int port); static boolean isValidAddress(String address); static boolean isLocalHost(String host); static boolean isAnyHost(String host); static boolean isInvalidLocalHost(String host); static boolean isValidLocalHost(String host); static InetSocketAddress getLocalSocketAddress(String host, int port); static String getLocalHost(); static String filterLocalHost(String host); static InetAddress getLocalAddress(); static String getLogHost(); static String getHostName(String address); static String getIpByHost(String hostName); static String toAddressString(InetSocketAddress address); static InetSocketAddress toAddress(String address); static String toURL(String protocol, String host, int port, String path); static final String LOCALHOST; static final String ANYHOST; }### Answer:
@Test public void getLogHost() throws Exception { String localHost = NetUtils.getLocalHost(); System.out.println(localHost); Assert.assertFalse("127.0.0.1".equals(localHost)); }
