Enable IPv6 in the ApsaraVideo VOD console so that clients can access CDN over IPv6. CDN then forwards the client's IPv6 address to your origin server.
Background
Most Alibaba Cloud CDN points of presence (POPs) support IPv6 requests. After you enable this feature, clients in an IPv6 network connect to the nearest IPv6-enabled POP. If the nearest POP does not support IPv6, clients automatically connect over IPv4.
Currently, POPs in regions outside the Chinese mainland, including China (Hong Kong), China (Macao), and China (Taiwan), do not support IPv6 configuration.
Procedure
-
Log on to the ApsaraVideo VOD console.
-
In the left-side navigation pane, choose Configuration Management > CDN Configuration > Domain Names.
-
On the Domain Names page, find the target domain and click Configure.
-
On the Basic Configuration tab, find the IPv6 feature.
-
Turn on the IPv6 switch.
When enabled, clients can access CDN over IPv6, and CDN forwards their IPv6 addresses to your origin server.
