Game Servers: High-Defense IP or High-Defense CDN? Split Modules by Protocol and Layer Your Access
Most games don't need to choose between high-defense IP and high-defense CDN; this article splits game services by protocol into Web modules and real-time connection modules, explains which modules use high-defense CDN and which use high-defense IP or game shield, and provides key points for combined deployment and the access sequence when under attack.
High-Defense IP: Change DNS or Change Ports? Understanding the Change Points and Onboarding Order by Business Type
When onboarding a high-defense IP, you usually change the user access entry point rather than the origin server's listening port: website businesses change DNS, while TCP/UDP businesses configure forwarding rules and then replace the client connection address.
Can a CDN Protect a UDP Game Server Under Attack?
Standard web CDNs cannot proxy UDP traffic, and while a few Layer 4 CDNs can reverse-proxy UDP, they suffer from latency sensitivity and plan restrictions. The mainstream choices for UDP game servers under DDoS attack are game shields (SDK encapsulation + hidden origin + millisecond-level scheduling) or Layer 4 high-defense IPs (full-port scrubbing but no protocol encryption), depending on whether the client can integrate an SDK and tolerance for latency.
Pros and Cons of Blocking Overseas UDP Traffic on Overseas High-Defense IP: How to Decide Among 4 Trade-offs
Blocking overseas UDP traffic on overseas high-defense IP can quickly stop reflection amplification attacks, but it also disrupts DNS, QUIC, gaming protocols, and more. This article breaks down the pros and cons and offers four strategic trade-offs.
Fighting AI Botnets and Tbps DDoS Floods: Enterprise High-Defense IP Selection and Deep Defense Architecture Guide
A guide to selecting high-defense IP and building a deep defense architecture against AI-powered botnets and multi-terabit DDoS attacks.
