If you need to detect a site whose IP address protection is enabled, you must configure an IP address whitelist based on the IPv4 and IPv6 address pools to ensure that the site monitoring feature is available.
You can call the DescribeSiteMonitorISPCityList operation to query the IPv4 and IPv6 addresses of the detection points that can be used to create site monitoring tasks. These detection points belong to a carrier. For information about the parameters in the DescribeSiteMonitorISPCityList operation, see DescribeSiteMonitorISPCityList.
