Using IPv6 IP addresses

Acquia Cloud supports IPv6 IP addresses. In order to use IPv6 for your website, you need to:

Enable SSL for your site

IPv6 support on Acquia Cloud Enterprise or Acquia Cloud Professional requires an Amazon Web Services Elastic Load Balancer (ELB) instance. For an ELB to be provisioned for an environment, you need to enable SSL support for the environment, which requires you to purchase and upload an SSL certificate as a legacy SSL certificate in the Acquia Cloud interface. Having an ELB enables IPv6 support. For Acquia Cloud Professional websites, there is an additional charge to reflect the cost of the ELB. For information about how to enable SSL, including how to upload a legacy SSL certificate, read Enabling SSL. If you want IPv6 support, but not SSL, contact Acquia Support. You may be able to use a self-signed SSL certificate to use with Acquia Cloud. You can then upload this self-signed certificate instead of purchasing a certificate. For more information, see Creating a self-signed SSL certificate.

In your DNS provider’s web interface, add the appropriate prefix to your domain name. In most cases, prefix your CNAME domain name with the dualstack prefix to support both IPv4 and IPv6 visitors. Prefix your CNAME domain name with the ipv6 prefix to support only IPv6 visitors. For example, suppose your website’s domain name is and your Prod environment’s URL is Set the CNAME entry for to
