Alibaba Cloud Content Delivery Network (CDN) is a distributed network built over the transport network and contains edge node clusters deployed in different regions. Alibaba Cloud CDN reduces workloads from origins to prevent network congestion. You can use Alibaba Cloud CDN to accelerate website content delivery in different regions or scenarios.

Alibaba Cloud CDN retrieves resources from origins and caches them on CDN nodes deployed across the world. When a user sends a resource request, the system does not need to send the request to the origin. Instead, the system automatically retrieves the resource cached on the CDN node closest to the user and returns it to the user. For information about how to connect to Alibaba Cloud CDN, see Quick start.

Currently, some CDN nodes can be accessed through IPv6.
