Anti-DDoS is an Internet network security solution designed to defend against Distributed Denial of Service (DDoS) attacks. It works by involving a multi-layered defense strategy to protect target servers from large-scale cyberattacks.

　　The working principle of high-defense IP:

　　1. Traffic detection and analysis: High-defense IP will monitor network traffic and identify abnormal traffic and attack traffic. It performs real-time analysis of traffic and detects potential DDoS attack traffic.

　　2. Blacklist and whitelist filtering: Anti-DDoS IP will perform blacklist and whitelist filtering on traffic based on preset rules. Legitimate traffic will be allowed to pass, while malicious attack traffic will be blocked.

　　3. Behavior analysis: High Defense IP will analyze the behavioral patterns in the traffic, such as connection frequency, packet size, etc., to identify whether there are abnormal attack behaviors.

　　4. Challenge-response mechanism: When the high-defense IP detects potential attack traffic, it will send a challenge to the IP address that initiated the request. Legitimate users may respond correctly to challenges, while attackers may not.

　　5. IP blocking: High-defense IP will block malicious IP addresses based on the characteristics of attack traffic to prevent their access. This helps reduce the impact of the attack.

　　6. Distributed defense: High-defense IP can be distributed on nodes in multiple geographical locations to form a distributed defense network. This disperses attack traffic and ensures network stability and availability.

　　Advantages of high-defense IP:

　　1. Powerful defense capabilities: High-defense IP has powerful defense capabilities and can effectively resist DDoS attacks of various sizes, including traditional DDoS attacks and new DDoS attack methods.

　　2. Real-time monitoring and analysis: High-defense IP will monitor network traffic in real time, analyze the traffic, and identify abnormal traffic and potential attack traffic so that defensive measures can be taken in a timely manner.

　　3. Automated defense: High-defense IP adopts an automated defense strategy, which can automatically adjust the defense strategy according to the characteristics of the attack to improve the accuracy and efficiency of defense.

　　4. Distributed defense network: High-defense IP can be deployed on nodes in multiple geographical locations to form a distributed defense network, which can disperse attack traffic and ensure network stability and availability.

　　Generally speaking, high-defense IP protects target servers from DDoS attacks through multi-layer defense strategies, from traffic detection to behavioral analysis, as well as challenge-response mechanisms and IP blocking. It identifies malicious traffic and blocks attacks, providing a more stable and secure network environment.
