About this network

A core network of Beijing Baidu Netcom Science and Technology, the entity behind Baidu, China's largest search engine. This ASN carries both Baidu's own services and Baidu AI Cloud (cloud.baidu.com) infrastructure.

What it's used for

• Hosting Baidu's search, apps, and Baidu AI Cloud offerings: cloud servers, storage, CDN, and AI/ML services for third-party customers.

Notable

• An IP here can be either Baidu's first-party infrastructure or a customer workload running on Baidu AI Cloud, so it identifies the host, not the operator of a given service.
• Registered in Beijing; primarily serves the China region.

Interesting

• Baidu AI Cloud is one of the larger domestic Chinese public clouds, competing with Alibaba Cloud and Tencent Cloud.
