Getting IPv4 and IPv6 programatically of Android Device with non deprecated methods, both when on Wifi and when on Carier's network

Question

I came across a few discussion about getting IPv4 and IPv6 addresses programmatically on Android. The problem with these other questions and answers is:

• Those question/answers are fairly old by now thus often deprecated. I am looking for a way to get it done in a non-deprecated way (for example, InetAddressUtils is deprecated and so are others).
• I want to know how to get both a IPv4 and IPv6 address when on Wifi or on the Carrier's network.

Is there someone who could tell me how to get it done in a short and neat way without a lengthy method (if that is possible)?

For ipv4,ipv6 You can use

   public String getIpv4() {
            try {
                for (Enumeration<NetworkInterface> en = NetworkInterface
                        .getNetworkInterfaces(); en.hasMoreElements(); ) {
                    NetworkInterface intf = en.nextElement();
                    for (Enumeration<InetAddress> enumIpAddr = intf
                            .getInetAddresses(); enumIpAddr.hasMoreElements(); ) {
                        InetAddress inetAddress = enumIpAddr.nextElement();
                        System.out.println("ip1--:" + inetAddress);
                        System.out.println("ip2--:" + inetAddress.getHostAddress());

                        if (!inetAddress.isLoopbackAddress() && inetAddress instanceof Inet4Address) {
                            String ipaddress = inetAddress.getHostAddress().toString();
                            return ipaddress;
                        }


                    }
                }
            } catch (Exception ex) {
                Log.e("IP Address", ex.toString());
            }
            return null;
        }

//ipv6
  public String getLocalIpV6() {
        try {
            for (Enumeration<NetworkInterface> en = NetworkInterface
                    .getNetworkInterfaces(); en.hasMoreElements(); ) {
                NetworkInterface intf = en.nextElement();
                for (Enumeration<InetAddress> enumIpAddr = intf
                        .getInetAddresses(); enumIpAddr.hasMoreElements(); ) {
                    InetAddress inetAddress = enumIpAddr.nextElement();
                    System.out.println("ip1--:" + inetAddress);
                    System.out.println("ip2--:" + inetAddress.getHostAddress());

                    if (!inetAddress.isLoopbackAddress() && inetAddress instanceof Inet6Address) {
                        String ipaddress = inetAddress.getHostAddress().toString();
                        return ipaddress;
                    }


                }
            }
        } catch (Exception ex) {
            Log.e("IP Address", ex.toString());
        }
        return null;
    }
