Method

StringgetLocalHost()
Returns the non-localhost IP address of the current machine. 
String address = null;
try {
    address = InetAddress.getLocalHost().getHostAddress();
    if (address.equals(LOCAL_HOST)) {
        Enumeration<NetworkInterface> interfaces = NetworkInterface.getNetworkInterfaces();
        boolean found = false;
        while (interfaces.hasMoreElements() && !found) {
            NetworkInterface e = interfaces.nextElement();
...
InetAddressgetLocalHost()
get Local Host 
try {
    return (InetAddress.getLocalHost());
} catch (Throwable e) {
    try {
        Enumeration nis = NetworkInterface.getNetworkInterfaces();
        while (nis.hasMoreElements()) {
            NetworkInterface ni = (NetworkInterface) nis.nextElement();
            Enumeration addresses = ni.getInetAddresses();
...
InetAddressgetLocalHost()
get Local Host 
try {
    return InetAddress.getLocalHost();
} catch (UnknownHostException e) {
    throw new AssertionError(e);
StringgetLocalHost()
get Local Host 
try {
    return InetAddress.getLocalHost().getCanonicalHostName();
} catch (final UnknownHostException uhe) {
    final Enumeration<NetworkInterface> interfaces = NetworkInterface.getNetworkInterfaces();
    while (interfaces.hasMoreElements()) {
        final NetworkInterface networkInterface = interfaces.nextElement();
        if (null != networkInterface) {
            final Enumeration<InetAddress> addresses = networkInterface.getInetAddresses();
...
InetAddressgetLocalHost()
Use this instead of InetAddress#getLocalHost() to prevent multiple lookups. 
if (localhost == null) {
    try {
        localhost = InetAddress.getLocalHost();
    } catch (UnknownHostException e) {
        throw new RuntimeException(e);
return localhost;
...
InetAddressgetLocalHost()
Methods returns InetAddress for localhost 
InetAddress addr;
try {
    addr = InetAddress.getLocalHost();
} catch (ArrayIndexOutOfBoundsException e) { 
    addr = InetAddress.getByName(null);
return addr;
InetAddressgetLocalHost()
get Local Host 
try {
    return InetAddress.getLocalHost();
} catch (UnknownHostException e) {
    return getLocalHostByName();
InetAddressgetLocalHost()
Smarter way to get localhost than InetAddress.getLocalHost. 
String osName = System.getProperty("os.name");
if (osName != null && osName.toLowerCase().contains("windows")) {
    return InetAddress.getLocalHost();
InetAddress loopback = null;
Enumeration<NetworkInterface> e = NetworkInterface.getNetworkInterfaces();
while (e.hasMoreElements()) {
    NetworkInterface i = e.nextElement();
...
InetAddressgetLocalHost()
Returns an InetAddress representing the address of the localhost. 
InetAddress localHost = InetAddress.getLocalHost();
if (!localHost.isLoopbackAddress()) {
    return localHost;
InetAddress[] addrs = getAllLocalUsingNetworkInterface();
for (InetAddress addr : addrs) {
    if (!addr.isLoopbackAddress() && !addr.getHostAddress().contains(":")) {
        return addr;
...
InetSocketAddressgetLocalHost()
get Local Host 
try {
    return new InetSocketAddress(InetAddress.getByName("192.168.0.10"), 0);
} catch (final UnknownHostException e) {
return null;
