BAI DNS is a public DNS service provided by my friend @Ponyxx. It has been running stably for more than half a year. Public DNS services are already very common. However, in the article "Collection and Summary of Common Public DNS Servers", most of the common DNS services are listed. So why introduce BAI DNS? Let me explain.

解析速度

BAI DNS uses Alibaba Cloud BGP servers, with an average response time of about 30ms. Therefore, if you are in China, the speed of DNS resolution is very fast.

Support for EDNS Intelligent Resolution

Here comes the key question, what is EDNS? When the intelligent resolution server receives a domain name query request from the client DNS server, it will intelligently determine whether the client DNS server belongs to the China Telecom network or China Unicom network, and return the corresponding IP address. This ensures that a domain name can be resolved to a China Telecom IP for China Telecom users, and to a China Unicom IP for China Unicom users. Yes, BAI DNS supports EDNS resolution.
