Update the CIDR Lists on your network

Using the proposed list of CIDR blocks, update your firewall's ACL before the Acknowledge-By Date on the main CIDR Lists screen (see Access the CIDR Lists application for more information).

In addition, if your end users access your network through a firewall, they will also have to update their firewall lists.

If you have any questions about the proposed list of CIDRs, please contact your ​Akamai​ representative.


It's possible that the list may change before you acknowledge it. Please review the available versions before acknowledging any changes.
