Introduction

CDN supports the blacklist rules. An IP address that is listed on the blacklist cannot access the corresponding domain.

Attentions:

You can use an IP network segment to add IP addresses to the blacklist.
Note
 For example, 127.0.0.1/24. 24 indicates that the first 24 bits in the subnet mask are used as effective bits, for example, 32-24=8 bits are used to express host numbers. In this way, the subnet can accommodate 2 ^ 8-2 = 254 hosts. And 127.0.0.1/24 indicates the IP network segment scope of 127.0.0.1~127.0.0.255.

Procedure

Enter the CDN domain name overview page, go to Domain Names page, select the domain name that you want to set up, and click Configure.
