Usage

From source file:Main.java

public static void main(String[] argv) throws Exception {
    byte[] ipAddr = new byte[] { 127, 0, 0, 1 };
    InetAddress addr = InetAddress.getByAddress(ipAddr);
    String hostnameCanonical = addr.getCanonicalHostName();
}

From source file:Main.java

public static void main(String[] argv) throws Exception {
    InetAddress addr = InetAddress.getByName("127.0.0.1");
    byte[] ipAddr = new byte[] { 127, 0, 0, 1 };
    addr = InetAddress.getByAddress(ipAddr);
    // Get the host name
    String hostname = addr.getHostName();
    // Get canonical host name
    String canonicalhostname = addr.getCanonicalHostName();

}

From source file:Main.java

public static void printAddressDetails(String host) throws Exception {

    System.out.println("Canonical  Host  Name: " + addr.getCanonicalHostName());

    int timeOutinMillis = 10000;
    System.out.println("isReachable(): " + addr.isReachable(timeOutinMillis));
    System.out.println("isLoopbackAddress(): " + addr.isLoopbackAddress());
