High-defense CDN and high-defense IP are two services used to defend against network attacks, but they have some differences in functions and applications. In practical applications, high-defense CDN and high-defense IP can be used in combination to provide more comprehensive network security protection. CDN is used to accelerate and distribute content while providing a certain degree of DDoS protection, while high-defense IP is used to directly protect the origin server from network attacks.

　　1. High-defense CDN:

　　Content distribution network: CDN is a service that improves website performance and availability by distributing content to multiple nodes around the world, allowing users to obtain content from nodes closer to them.

　　Mitigating DDoS attacks: High-defense CDNs are often resistant to DDoS attacks because they can disperse traffic and direct requests to the nearest node, thereby reducing the impact on the origin server.

　　Accelerate content transmission: CDN is mainly used to accelerate static resources (such as images, CSS, JavaScript) and increase the transmission speed of these resources, thereby improving user experience.

　　2. High defense IP:

　　IP address defense: High-defense IP focuses on protecting specific IP addresses by providing protection services to prevent various network attacks, especially DDoS attacks.

　　Direct connection to the source server: Anti-DDoS IP passes all incoming traffic through its protective layer before connecting to the source server. It directly protects the IP address of the origin server, making the origin server more difficult to attack.

　　Applicable to all types of traffic: High-defense IP can not only defend against static resource attacks, but also defend against dynamic content and other types of network traffic.

　　Difference and comprehensive use:

　　1. Different application scenarios:

　　High-defense CDN is mainly used to accelerate static content transmission and improve website performance, and also has certain DDoS protection functions.

　　High Defense IP focuses on protecting specific IP addresses from various network attacks, especially DDoS attacks.

　　2. Different protection depths:

　　The protection of high-defense CDN mainly focuses on the distribution nodes to reduce the burden on the source server, but not all attacks can be effectively protected.

　　High-defense IP provides deeper protection and protects directly at the source server and network level.

　　Generally speaking, choosing between high-defense CDN and high-defense IP depends on the specific application requirements and attack scenarios. Combining these two services can provide stronger network security protection.
