The IP defense of high-defense cloud servers uses a series of technologies and strategies to protect servers from various network attacks. The following are some common methods of high-defense cloud server IP defense:

　　DDoS defense:

　　High-defense cloud servers detect and filter DDoS attack traffic by using professional DDoS protection equipment or services. These devices or services can analyze traffic patterns and identify and block abnormal traffic to ensure that normal traffic can reach the server.

　　IP filtering and blocking:

　　The high-defense cloud server can filter and block IPs based on rules such as blacklists, whitelists, and IP address segments. Malicious IP addresses will be blocked from accessing the server, reducing the impact of attack traffic.

　　Network traffic cleaning:

　　The high-defense cloud server uses network traffic cleaning technology to conduct in-depth analysis and cleaning of incoming traffic. These technologies can identify and filter out malicious traffic, including DDoS attacks, CC attacks, scanning and crawlers, etc., ensuring that only normal traffic reaches the server.

　　Bandwidth expansion:

　　High-defense cloud servers usually provide high-bandwidth network connections to withstand large-scale traffic impacts. Bandwidth expansion can ensure that the server can handle a large number of requests and traffic, reducing the impact of bandwidth bottlenecks on server performance.

　　Real-time monitoring and response:

　　High-defense cloud servers can quickly identify abnormal situations and take corresponding defensive measures by monitoring network traffic and server status in real time. This can include automatically blocking attack source IPs, adjusting defense strategies, etc.

　　Generally speaking, high-defense cloud servers protect servers from various network attacks by comprehensively applying a variety of defense technologies and strategies. The purpose of these defense measures is to ensure the stability, reliability and security of the server, ensure that normal traffic can reach the server, and effectively resist malicious attacks.
