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);
    System.out.println(Arrays.toString(addr.getAddress()));
}

From source file:Main.java

public static void main(String[] argv) throws Exception {
    InetAddress addr = InetAddress.getByName("java-tips.org");
    byte[] ipAddr = addr.getAddress();

    // Convert to dot representation
    String ipAddrStr = "";
    for (int i = 0; i < ipAddr.length; i++) {
        if (i > 0) {
            ipAddrStr += ".";
        }//  w  w  w  .ja  va 2s. c  o  m
        ipAddrStr += ipAddr[i] & 0xFF;
    }

}

From source file:Main.java
