Anti-DDOS IP and high-defense CDN (Content Delivery Network) are two different services for network security and performance optimization. They have the following differences:

　　Different uses:

　　High -defense IP: High -defense IP is mainly used for defensive distributed refusal service attacks (DDOS attacks). It is a kind of network security service, which aims to protect your network server from large -scale DDOS attacks and ensure the availability of your online services.

　　High -defense CDN: High -defense CDN is a content distribution network service, which aims to provide faster website loading speed and reduce network delay. It can improve the user's access experience by copying your content to the server that is distributed globally and to the user's nearest server.

　　Different defensive objects:

　　High -defense IP: Attacks for network layers and transmission layers, such as Syn/ACK Flood, UDP Flood, ICMP Flood, etc. DDOS attacks.

　　High -defense CDN: It is mainly used to relieve application layer attacks, such as HTTP request attack, SQL injection, XSS attack, etc. It reduces the server load by cache and distribution content and accelerates content transmission.

　　Performance and speed:

　　High -defense IP: It mainly focuses on defense attacks, and usually does not directly provide content distribution services. Therefore, it may not provide content acceleration and network performance optimization like high -defense CDN.

　　High Defense CDN: In addition to providing DDOS protection, it can also accelerate content transmission, provide faster website loading speed, and reduce network latency through global distribution content.

　　Pricing method:

　　High -defense IP: Usually, the cost is mainly related to the defense bandwidth and cleaning costs. The cost is mainly related to the protection capacity.

　　High -defense CDN: The billing method may be related to CDN flow usage and service coverage area.

　　Deployment method:

　　High -defense IP: Usually deployed directly on your network server to protect your server.

　　High -defense CDN: It is a distributed service that needs to configure the CDN rules and upload the content to the server of the CDN provider.

　　In summary, high -defense IP and high -defense CDN are two different services, which are used for network security and content distribution. You can choose to use one or two of them according to your needs to improve the performance and security of your online service.
