Method

StringgetHost(final String address)
Returns host for the specified address. 
final URL url = getURL(address);
return url != null ? url.getHost() : null;
StringgetHostAddress()
Returns the textual presentation of the local host IP address. 
return java.net.InetAddress.getLocalHost().getHostAddress();
StringgetHostAddress()
get Host Address 
String strIP = "";
try {
    InetAddress thisIp = InetAddress.getLocalHost();
    strIP = thisIp.getHostAddress();
} catch (Exception e) {
    e.printStackTrace();
    strIP = "";
return strIP;
StringgetHostAddress()
get Host Address 
try {
    return InetAddress.getLocalHost().getHostAddress();
} catch (UnknownHostException uhe) {
    throw new Error("Couldn't get this host address, which is needed to register in the database");
StringgetHostAddress()
get Host Address 
try {
    return (InetAddress.getLocalHost()).getHostAddress();
} catch (UnknownHostException uhe) {
    String host = uhe.getMessage();
    if (host != null) {
        int colon = host.indexOf(':');
        if (colon > 0) {
            return host.substring(0, colon);
...
StringgetHostAddress()
Get the ip address of local host. 
DatagramSocket ds = new DatagramSocket();
ds.connect(InetAddress.getByName(DUMMY_OUT_IP), 80);
InetAddress localAddress = ds.getLocalAddress();
if (localAddress.getHostAddress().equals("0.0.0.0")) {
    localAddress = InetAddress.getLocalHost();
return localAddress.getHostAddress();
StringgetHostAddress()
get Host Address 
final Enumeration<NetworkInterface> interfaces = NetworkInterface.getNetworkInterfaces();
while (interfaces.hasMoreElements()) {
    final NetworkInterface current = interfaces.nextElement();
    if (!current.isUp() || current.isLoopback() || current.isVirtual()) {
        continue;
    final Enumeration<InetAddress> addresses = current.getInetAddresses();
    while (addresses.hasMoreElements()) {
...
short[]getHostAddress()
Gets the host address, works around byte[] getAddress() looking negative 
short[] address = new short[4];
try {
    InetAddress netAddress = InetAddress.getLocalHost();
    String ipAddress = netAddress.getHostAddress();
    int beginIndex = 0;
    int endIndex = ipAddress.indexOf('.');
    address[0] = (short) Integer.parseInt(ipAddress.substring(beginIndex, endIndex));
    beginIndex = endIndex + 1;
...
StringgetHostAddress()
get Host Address 
List<String> addresses = new LinkedList<>();
Enumeration<NetworkInterface> interfaces = NetworkInterface.getNetworkInterfaces();
while (interfaces.hasMoreElements()) {
    NetworkInterface n = (NetworkInterface) interfaces.nextElement();
    Enumeration<InetAddress> ee = n.getInetAddresses();
    while (ee.hasMoreElements()) {
        InetAddress i = (InetAddress) ee.nextElement();
        if (i instanceof Inet4Address) {
...
InetAddressgetHostAddress()
Get the host IP address Use env(IFACE) to select an interface or env(IP) to select a specific address to prefer IPv6 use: java.net.preferIPv6Stack=true 
boolean ipv6 = false;
String pv4 = System.getProperty("java.net.preferIPv4Stack");
String pv6 = System.getProperty("java.net.preferIPv6Stack");
if (pv4 != null && pv4.equals("false")) {
    ipv6 = true;
if (pv6 != null && pv6.equals("true")) {
    ipv6 = true;
