This topic describes how to enable the IPv6 feature in the Alibaba Cloud Dynamic Route for CDN (DCDN) console. After you enable IPv6 in the console, IPv6 clients can send IPv6 requests to DCDN. DCDN can include the IPv6 information of the clients in back-to-origin requests.

Background information

Most of the DCDN nodes support IPv6. You can enable this feature for an accelerated domain when you configure features for the domain.

After IPv6 is enabled, clients can send IPv6 requests to the DCDN nodes that are nearest to the clients over an IPv6 network if these DCDN nodes support IPv6. If the nearest DCDN nodes do not support IPv6, the clients can access the DCDN nodes by sending IPv4 requests.


  1. Log on to the DCDN console.
  2. In the left-side navigation pane, click Domain Names.
  3. On the Domain Names page, find the domain name that you want to manage, and click Configure in the Actions column.
  4. In the left-side navigation pane of the page that appears, click Advanced Settings.
  5. Turn on IPv6.

    After you enable IPv6, a client can send IPv6 requests to DCDN nodes. Requests that are redirected from DCDN nodes to your origin server can include the IPv6 information of the client.
