Dynamic Content Delivery Network:Check IP addresses

Last Updated:Dec 25, 2023

After you add an origin server to Dynamic Content Delivery Network (DCDN), you can use the IP address check feature to check whether the IP address that the client accesses belongs to a POP and determine whether the acceleration takes effect.

Scenarios

This feature is suitable for the following scenarios:

  • 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.

    If the IP address belongs to a POP, provide the IP address of the POP when you submit a ticket to handle the exception. If the IP address does not belong to a POP, the exception may be caused by the network connection of the Internet service provider (ISP). In this case, contact the ISP to obtain technical support.

Procedure

  1. Log on to the DCDN console.

  2. In the left-side navigation pane, choose Tools > IP Check. Select a tab based on your business requirements.
