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.
Origin IP ACL is available for use with several Akamai products. So, its setup in your delivery configuration can vary. But, the list of IP addresses it uses is fixed. Check out the Origin IP ACL user documentation for full details.
