1 获取局域网IP地址

    String hostAddress = InetAddress.getLocalHost().getHostAddress();
        System.out.println(hostAddress);//192.168.1.55

2 获取全部 IPV4/IPV6 IP地址

 private static List<String> getIpAddress() throws SocketException {
        List<String> list = new LinkedList<>();
        Enumeration enumeration = NetworkInterface.getNetworkInterfaces();
        while (enumeration.hasMoreElements()) {
            NetworkInterface network = (NetworkInterface) enumeration.nextElement();
            if (network.isVirtual() || !network.isUp()) {
                continue;
            } else {
                Enumeration addresses = network.getInetAddresses();
                while (addresses.hasMoreElements()) {
                    InetAddress address = (InetAddress) addresses.nextElement();
                    if (address != null && (address instanceof Inet4Address || address instanceof Inet6Address)) {
                        list.add(address.getHostAddress());
                    }
                }
            }
        }
        return list;
    }

3 获取全部存放本机IP地址

private static List<String> getIpAddress() throws SocketException {
        List<String> list = new LinkedList<>();
        Enumeration enumeration = NetworkInterface.getNetworkInterfaces();
        while (enumeration.hasMoreElements()) {
            NetworkInterface network = (NetworkInterface) enumeration.nextElement();
            Enumeration addresses = network.getInetAddresses();
            while (addresses.hasMoreElements()) {
                InetAddress address = (InetAddress) addresses.nextElement();
                if (address != null && (address instanceof Inet4Address || address instanceof Inet6Address)) {
                    list.add(address.getHostAddress());
                }
            }
        }
        return list;
    }
