Method

StringgetIpAddress()
get Ip Address 
String ip = null;
try {
    Enumeration<NetworkInterface> er = NetworkInterface.getNetworkInterfaces();
    while (er.hasMoreElements()) {
        NetworkInterface ni = er.nextElement();
        if (ni.getName().startsWith("eth") || ni.getName().startsWith("bond")) {
            List<InterfaceAddress> list = ni.getInterfaceAddresses();
            for (InterfaceAddress interfaceAddress : list) {
...
StringgetIpAddress()
Return a non loopback IPv4 address for the machine running this process. 
try {
    for (Enumeration<NetworkInterface> enumNic = NetworkInterface.getNetworkInterfaces(); enumNic
            .hasMoreElements();) {
        NetworkInterface ifc = enumNic.nextElement();
        if (ifc.isUp()) {
            for (Enumeration<InetAddress> enumAddr = ifc.getInetAddresses(); enumAddr.hasMoreElements();) {
                InetAddress address = enumAddr.nextElement();
                if (address instanceof Inet4Address && !address.isLoopbackAddress()) {
...
StringgetIPAddress(boolean useIPv4)
Get IP address from first non-localhost interface 
try {
    List<NetworkInterface> interfaces = Collections.list(NetworkInterface.getNetworkInterfaces());
    for (NetworkInterface intf : interfaces) {
        List<InetAddress> addrs = Collections.list(intf.getInetAddresses());
        for (InetAddress addr : addrs) {
            if (!addr.isLoopbackAddress()) {

StringgetIPAddress(final String hostName)
Retrieves a host's IP address; see SOAPClient.getLocalAddr() for local IP 
try {
    return InetAddress.getByName(hostName).getHostAddress();
} catch (final Exception e) {
    throw toRuntimeException(e);
StringgetIPAddress(NetworkInterface e)
get IP Address 
Enumeration<InetAddress> a = e.getInetAddresses();
for (; a.hasMoreElements();) {
    InetAddress addr = a.nextElement(); 
    addr = a.nextElement(); 
    return addr.getHostAddress();
return null;
StringgetIPAddress(String hostname)

Determines a host's IP address in string form.

String ipAddr = null;
try {
    InetAddress ia = InetAddress.getByName(hostname);
    ipAddr = ia.getHostAddress();
} catch (UnknownHostException e) {
return ipAddr;
StringgetIpAddress(String server)
Perform a lookup of server returning the associated ip address. 
if (server == null)
    return null;
try {
    InetAddress addr = InetAddress.getByName(server);
    return addr.getHostAddress();
} catch (UnknownHostException uhe) {
    return null;
