Method

longgetIP(InetAddress ip)
get IP 
byte[] b = ip.getAddress();
return b[0] << 24L & 0xff000000L | b[1] << 16L & 0xff0000L | b[2] << 8L & 0xff00 | b[3] << 0L & 0xff;
StringgetIP(InetAddress ip)
get IP 
return ip.getHostAddress().replace("/", "");
StringgetIP(InetAddress ip)
get IP 
return ip.getHostAddress().replace("/", "");
longgetIPAsLong(InetAddress address)
A convenient method that accepts an IP address represented by a byte[] of size 4 and returns this as a long representation of the same IP address. 
return getIPAsLong(address.getAddress());
StringgetIPAsString(InetAddress addr)
Returns a human readable IP address for the given address. 
byte[] ip = addr.getAddress();
StringBuilder sb = new StringBuilder();
for (int i = 0; i < ip.length; i++) {
    if (i != 0) {
        sb.append(".");
    sb.append(ip[i] & 0xFF);
return sb.toString();
InetAddressgetIPv4LocalNetMask(InetAddress ip, int netPrefix)
Gets network mask for the IP address and network prefix specified. 
try {
    int shiftby = (1 << 31);
    for (int i = netPrefix - 1; i > 0; i--) {
        shiftby = (shiftby >> 1);
    String maskString = Integer.toString((shiftby >> 24) & 255) + "."
            + Integer.toString((shiftby >> 16) & 255) + "." + Integer.toString((shiftby >> 8) & 255) + "."
            + Integer.toString(shiftby & 255);
...
VectorgetIPv6InetAddresses(NetworkInterface networkInterface)
Retrieves a list of all IPv6 addresses assigned to one interface. 
Enumeration e;
Vector result = new Vector();
e = networkInterface.getInetAddresses();
while (e.hasMoreElements()) {
    InetAddress currentAddress = (InetAddress) e.nextElement();
    if (currentAddress instanceof Inet6Address) {
        result.add(currentAddress);
return result;
InetAddressgetLocalInetAddress()
get Local Inet Address 
NetworkInterface iface = null;
if (System.getProperty("os.name").compareTo("Linux") != 0)
    try {
        return InetAddress.getLocalHost();
    } catch (UnknownHostException e1) {
        e1.printStackTrace();
try {
...
InetAddressgetLocalInetAddress()
Returns an IP address of the device to be used for local communication on the subnet. 
try {
    List<InetAddress> addresses = getIPAddresses();
    for (InetAddress a : addresses) {
        if (a instanceof Inet6Address && a.isLinkLocalAddress()) {
            return a;
    for (InetAddress a : addresses) {
...
InetAddressgetLocalInetAddress()
Retrieve the first validated local ip address(the Public and LAN ip addresses are validated). 
Enumeration<NetworkInterface> enu = NetworkInterface.getNetworkInterfaces();
while (enu.hasMoreElements()) {
    NetworkInterface ni = enu.nextElement();
    if (ni.isLoopback()) {
        continue;
    Enumeration<InetAddress> addressEnumeration = ni.getInetAddresses();
    while (addressEnumeration.hasMoreElements()) {
...
