Scenario 1: After you configure DCDN, you can use this feature to check whether the IP address that is requested by the client belongs to a POP and whether the acceleration takes effect.
Scenario 2: If an exception occurs when a user accesses a page, you can use this feature to check whether a specific IP address belongs to a POP and troubleshoot the exception.
