如何获得内网IP

[mmrwbb]

如何获得内网IP？并将它最后一位截取出来 比如 内网IP 10.0.0.101 把101取出来

[434gfhghghg444545]

在servlet里面有个方法可以获取客户端的ip,然后你用substring截取

[liuhua_sun]

你只要获取自己机子上的还是整个内网的都需要获取啊？

访问页面机器的IP。。

public static void main(String[] args) {
		Enumeration<NetworkInterface> netInterfaces = null;
		try {
			netInterfaces = NetworkInterface.getNetworkInterfaces();
			while (netInterfaces.hasMoreElements()) {
				NetworkInterface ni = netInterfaces.nextElement();
				System.out.println("DisplayName:" + ni.getDisplayName());
				System.out.println("Name:" + ni.getName());
				Enumeration<InetAddress> ips = ni.getInetAddresses();
				while (ips.hasMoreElements()) {
					System.out.println("IP:"
							+ ips.nextElement().getHostAddress());
				}
			}
		} catch (Exception e) {
			e.printStackTrace();
		}
	}

String str=request.getRemoteAddr();
string laststr=str.substring(str.lastIndexOf("."));

[小一郎]

用request对象里的getRemoteAddr()方法

String str=request.getRemoteAddr(); 
string laststr=str.substring(str.lastIndexOf("."));

6楼 截出来是".101"啊

[BearRui]

String str=request.getRemoteAddr();
string laststr=str.substring(str.lastIndexOf(".")+1);

[miaosha2009]
