    CloudMonitor:Query the IP addresses of detection points

    Last Updated:Mar 05, 2025

    This topic describes the IP address pool of detection points for the site monitoring feature. To monitor a site for which IP address protection is enabled, you must configure an IP address whitelist based on the IP address pool.

    You can call the DescribeSiteMonitorISPCityList operation to query the IPv4 and IPv6 addresses of the detection points that are provided by carriers.

    Note

    The following CIDR blocks are used by Alibaba Cloud for internal networks. To allow access from your internal IP addresses, you can add them to the IP address whitelist.

    • 10.0.0.0/8

    • 172.16.0.0/12

    • 192.168.0.0.16

    • 100.64.0.0/10

    If you are unable to receive an alert recovery notification for site monitoring as expected, you can check whether your firewall has blocked the request for the alert recovery notification. You can call the DescribeSiteMonitorISPCityList operation to query the IP addresses of carrier detection points. Then, you can add the IP addresses to your whitelist.
