Evolution and Practice of iQIYI Internal DNS Architecture in Hybrid Cloud

iQIYI’s internal DNS evolved from a simple private‑cloud master/slave design into a multi‑layer Anycast architecture and, finally, a hybrid‑cloud solution that unifies private and public cloud name resolution through directional forwarding, proxy bridging, and automated management, delivering secure, low‑latency, globally consistent service.

Can a Country Be Erased from the Internet by Blocking Root DNS Servers?

The article explains how the Domain Name System works, describes the hierarchical structure of DNS including root, top‑level, and authoritative servers, and argues that even if root servers were blocked a nation would not disappear from the Internet because of distributed mirrors and anycast technology.

Anycast Technology Overview and Its Application in Internal DNS System Deployment

Anycast assigns a single IP to multiple distributed DNS nodes, automatically routing queries to the nearest healthy server, which balances load, mitigates DDoS, and provides sub‑second failover; iQIYI’s internal tests confirmed UDP and TCP compatibility, enabling a self‑healing DNS deployment across data centers that cuts operational complexity and prepares for broader service use.
