If you enable IPv6, clients that support IPv6 can have access to live streams over IPv6.
Background information
Alibaba Cloud CDN nodes that are deployed in the Chinese mainland support IPv6. You can enable IPv6 for a domain name when you configure the domain name.
If clients are deployed on an IPv6 network and the nearest CDN nodes support IPv6, the clients can send IPv6 requests to the CDN nodes after you enable IPv6. If the nearest CDN nodes do not support IPv6, the clients can send IPv4 requests to the CDN nodes.
Note CDN nodes that are deployed in regions outside the Chinese mainland, including China
(Hong Kong), China (Macao), and China (Taiwan), do not support IPv6.
