Just like access control lists (ACLs) in networking, this capability refers to having the ability to define access rules at transport level, for example, defining an access rule that only allows calls to an API that come from a specific IP range, or the opposite: allowing all callers but those coming from a specific range.
This capability can be useful, for example, in scenarios where it's required to restrict access to an API based on a given region (for example, only calls originating from IPs belonging to EU countries are allowed). Because there are ways to get around IP restrictions, this capability should not be used as the only means to control access to an API.
