ETP allows you to create are two broad categories of lists: Block Lists and Exception Lists.
Block lists are used to define whether a policy should block access or simply monitor access when users make requests to outside resources.
Exception lists are used to define exceptions to the policy actions defined for the Block lists. The ETP Proxy does not scan the domains, IP addresses, URLs, or file hashes in Exception lists.
Each entry in a list is counted separately. For example, in a custom list, each domain and IP address is counted as a separate entry. ETP allows you to have a maximum of 200,000 list entries.
An enterprise can create a maximum of 100 lists. If your organization needs to create more lists, contact your Akamai representative.
You must deploy your work after creating, modifying, or deleting a list. The deployment takes approximately 20-30 seconds.
