Performance Comparison of Major Public DNS Services in China
Testing 150 popular domains from four Chinese cities shows OneDNS public version consistently leads with 9‑19 ms latency, followed closely by Alibaba DNS, while 114DNS, Tencent DNSPod and 360DNS lag behind, prompting users to seek free alternatives as Alibaba’s unlimited service becomes paid.
Alibaba Cloud's public DNS service will start charging for unlimited speed and excess queries from September 30, 2024, prompting users to look for free alternatives.
The article evaluates several popular Chinese public DNS providers—114DNS, OneDNS (public version), Tencent DNSPod, 360DNS, and Alibaba DNS—by measuring response times for 150 commonly used domains across four locations (Beijing, Shanghai, Guangzhou, Chengdu).
Testing methodology: each domain is queried twice at the same location to ensure caching, and the average resolution time is recorded, providing a fair comparison of cached‑hit performance.
Results show that OneDNS public version consistently achieves the fastest average latency (≈9‑19 ms), followed by Alibaba DNS (≈11‑23 ms), while 114DNS and 360DNS are slower. Detailed average times per city are presented in tables.
Based on the measurements, the DNS services are grouped into two tiers: the first tier (OneDNS public and Alibaba DNS) and the second tier (114DNS, Tencent DNSPod, 360DNS). The article invites readers to share additional free, unlimited DNS recommendations.
