Origin IP access control list, or "Origin IP ACL" helps protect your origin by restricting traffic to it through a small and stable list of IP addresses. Once Origin IP ACL is in place, your origin server will only honor requests from ​Akamai​ edge servers that are issued from one of these addresses.

How to set up Origin IP ACL

Origin IP ACL is available for use with several ​​Akamai​​ products. For set up instructions, check out the Origin IP ACL user documentation.
