DNS Landscape in China
China's DNS environment is unique due to the Great Firewall (GFW) content filtering system. International DNS resolvers like Cloudflare and Google are often blocked or heavily throttled, making them unreliable inside China. Chinese users should use local DNS providers for domestic sites and carefully evaluate international options for foreign site access.
Local Chinese DNS providers include 114DNS, AliDNS (Alibaba), Baidu DNS, DNSPod (Tencent), and OneDNS. These providers operate servers within China and are not affected by GFW limitations. They provide fast resolution for Chinese domains and comply with local regulations.
Local Chinese DNS Providers
114DNS (114.114.114.114) is the most popular public DNS in China. It averages 5-10 ms in Beijing and Shanghai with high reliability. AliDNS (223.5.5.5) from Alibaba averages 6-12 ms with strong performance for Alibaba-hosted sites. Baidu DNS (180.76.76.76) averages 8-15 ms. DNSPod from Tencent averages 7-12 ms.
International DNS in China
Cloudflare 1.1.1.1 is intermittently accessible in China with high latency (100-300 ms). Google 8.8.8.8 is generally blocked or heavily throttled. Quad9 9.9.9.9 has limited accessibility. For international site access, Chinese users may need to combine a local DNS resolver with a VPN or proxy for sites that are restricted.
