Last Updated:Jun 21, 2023


Alibaba Cloud Domain Name System (DNS) is a secure, fast, stable, and scalable authoritative DNS service. This service can route user requests to required websites or application servers for customers in a convenient manner.


  • High stability

Alibaba Cloud DNS servers around the world back up each other to deliver SLA-guaranteed availability of 100%. Network-wide data is synchronized and updated in a timely manner to ensure data consistency.

  • High security

With more than 10 Tbit/s bandwidth and multiple large traffic scrubbing centers across the globe, Alibaba Cloud DNS can defend against DDoS attacks of over 100 million DNS queries per second.

  • Fast speed

Alibaba Cloud DNS servers are deployed around the world. This accelerates DNS resolution and reduces resolution latency because DNS queries are routed to the nearest DNS servers available.


Alibaba Cloud DNS servers are available in US (Virginia), US (Silicon Valley), India, Indonesia, Malaysia, Australia, Singapore, Japan, UAE, Germany, UK, Hong Kong (China), Beijing, Shanghai, Shenzhen, Hangzhou, Heyuan, Zhangjiakou, and Chengdu.

  • High performance

Alibaba Cloud DNS can deliver thousands of domain name changes to global nodes within 1 second, and can process more than 100 billion DNS queries per day.


Alibaba Cloud DNS consists of the control layer and the resolution layer.

  • The control layer works with the console and OpenAPI to achieve the functions of adding, deleting, modifying, querying, and storing data such as DNS resolution data, configuration data, and log data. The control layer is located in the China (Zhangjiakou) region.

  • The resolution layer provides external services by working with the DNS server clusters that are deployed around the world. The resolution layer receives the DNS record data distributed from the control layer and responds to the queries for the DNS record data. The resolution layer covers the major continents and regions around the world.
