Android IPV6获取方式

下面的代码中我做了校验真实的ipv6获取ipv6去除％后面的值然后通过冒号校验位数，然后截取第一段判断是否包括fe或者fc包括就表示假的

//ipv6
        public static 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();
                        // logger.error("ip1       " + inetAddress);
                        logger.error("ip1  " + inetAddress.getHostAddress());
                     /*   logger.error("getHostName  " + inetAddress.getHostName());
                        logger.error("getCanonicalHostName  " + inetAddress.getCanonicalHostName());
                        logger.error("getAddress  " + Arrays.toString(inetAddress.getAddress()));
                        logger.error("getHostAddress  " + inetAddress.getHostAddress());*/
    
                        if (!inetAddress.isLoopbackAddress() && inetAddress instanceof Inet6Address) {
                            return inetAddress.getHostAddress();
                        }
    
    
                    }
                }
            } catch (Exception ex) {
                Log.e("IP Address", ex.toString());
            }
            return null;
        }
        public static String getlocalIp() {
            String ip;
    
            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();
                        if (!inetAddress.isLoopbackAddress() && !inetAddress.isLinkLocalAddress()) {
    //                           ip=inetAddress.getHostAddress().toString();
                            System.out.println("ip==========" + inetAddress.getHostAddress());
                            return inetAddress.getHostAddress();
    
                        }
                    }
                }
            } catch (SocketException ignored) {
    
            }
            return null;
        }
    
        public static String validateV6() {
           
           new Thread(new Runnable() {
                @Override
                public void run() {
                    hostIp6 = getLocalIpV6();
                }
            }).start();
    
            //过滤找到真实的ipv6地址
            logger.error("v6 validateV6 " + hostIp6);
            if (hostIp6 != null && hostIp6.contains("%")) {
                String[] split = hostIp6.split("%");
                String s1 = split[0];
                logger.error("v6 remove % is " + s1);
    
                if (s1 != null && s1.contains(":")) {
                    String[] split1 = s1.split(":");
                    if (split1.length == 6||split1.length==8) {
                        if (split1[0].contains("fe") || split1[0].contains("fc")) {
                            return "0.0.0.0";
                        } else {
                            return s1;
                        }
                    }
                }
            }
            return "0.0.0.0";
        }
