You can configure an IP filtering policy for a managed API or custom API. The IP filtering policy designates the range of computer IP addresses that are allowed or that are denied permission to invoke the API.
If an IP filtering policy is not defined for an API, or if
API Manager
doesn't find any matches with the API-specific policy,
API Manager
applies the organizational IP filtering policy to the API.
When the policy is breached,
API Manager
logs an event in the even log. For more information about the event log, see
Event log.
