Android API-23: InetAddressUtils replacement

Question

Switching to Android Marshmallow API, I was using org.apache.http.conn.util.InetAddressUtils for InetAddressUtils.isIPv4Address(ipAddress) in a code to list all IPs from a device.

As part of the API-23 changes, the InetAddressUtils class is now gone.

How can I replace the below code now?

public static String ipAddress() {
    try {
        for (final Enumeration<NetworkInterface> enumerationNetworkInterface = NetworkInterface.getNetworkInterfaces(); enumerationNetworkInterface.hasMoreElements();) {
            final NetworkInterface networkInterface = enumerationNetworkInterface.nextElement();
            for (Enumeration<InetAddress> enumerationInetAddress = networkInterface.getInetAddresses(); enumerationInetAddress.hasMoreElements();) {
                final InetAddress inetAddress = enumerationInetAddress.nextElement();
                final String ipAddress = inetAddress.getHostAddress();
                if (! inetAddress.isLoopbackAddress() && InetAddressUtils.isIPv4Address(ipAddress)) {
                    return ipAddress;
                }
            }
        }
        return null;
    }
    catch (final Exception e) {
        LogHelper.wtf(null, e);
        return null;
    }
}

Like I interprete from the comments you can replace that function with this comparison:

inetAddress instanceof Inet4Address

so your code would end in:

if(!inetAddress.isLoopbackAddress() && inetAddress instanceof Inet4Address) {

Update from 2020
Keep in mind that your user can also have IPv6 enabled. In that case you need to check for Inet6Address too.
