域名防洪源码

域名防洪源码是一种有效的网络安全机制，可以防止恶意攻击和DDoS攻击。这篇文章将介绍域名防洪源码的实现和原理，并提供代码示例。

什么是域名防洪？

域名防洪是一种网络安全机制，用于防止恶意攻击和DDoS攻击。这种攻击通过向目标网站发送大量的请求流量，使其无法响应合法用户的请求。域名防洪机制可以检测和限制来自特定IPv4/IPv6地址的请求，从而提高网络安全和稳定性。

如何实现域名防洪？

域名防洪源码可以使用各种编程语言编写，例如C、C ++、Java、Python等。以下是一个示例代码，用于限制特定IP地址的请求：

import java.net.InetAddress;
import java.util.HashMap;
import java.util.Map;

public class DomainFloodProtection {
    private Map<InetAddress, Long> requests = new HashMap<>();
    private final int LIMIT = 5;
    private final long INTERVAL = 60 * 1000;

    public boolean blocked(InetAddress address) {
        long now = System.currentTimeMillis();

        if(requests.containsKey(address)) {
            long lastRequestTime = requests.get(address);
            if(now - lastRequestTime < INTERVAL) {
                requests.put(address, now);
                return true;
            }
            else {
                requests.put(address, now);
                return false;
            }
        }
        else {
            requests.put(address, now);
            return false;
        }
    }

    public static void main(String[] args) {
        DomainFloodProtection protection = new DomainFloodProtection();

        // Test blocked IP address
        System.out.println("Blocked IP Address: " + protection.blocked(InetAddress.getByName("192.168.0.1")));
        System.out.println("Blocked IP Address: " + protection.blocked(InetAddress.getByName("192.168.0.1")));
        System.out.println("Blocked IP Address: " + protection.blocked(InetAddress.getByName("192.168.0.1")));
        System.out.println("Blocked IP Address: " + protection.blocked(InetAddress.getByName("192.168.0.1")));
        System.out.println("Blocked IP Address: " + protection.blocked(InetAddress.getByName("192.168.0.1")));
        System.out.println("Blocked IP Address: " + protection.blocked(InetAddress.getByName("192.168.0.1")));

        // Test un
