Security Control:Apply for adding IP addresses to the global whitelist of Alibaba Cloud Security

Last Updated:Jun 22, 2026

Alibaba Cloud monitors and blocks suspicious actions in real time. If you use a third-party CDN or security vendor to forward requests or perform security scans, Alibaba Cloud Security may treat these behaviors as suspicious and block access. CDN and security vendors can apply to add their IP addresses to the global whitelist to avoid such disruptions.

CDN and security vendors (the applicant) can apply to add the IP addresses of their products to the global whitelist of Alibaba Cloud Security basic protection by following this procedure.

Note If you only want to configure a whitelist for all of your ECS instances, see Configure an access whitelist in Security Control.

  • A list of the IP addresses to be added to the whitelist. If the list is long, provide an official link or send it as an email attachment.
  • Usage descriptions of the IP addresses.
  • A commitment to comply with applicable laws, regulations, and Alibaba Cloud policies. The applicant must commit to not launching any type of attack against Alibaba Cloud users. If the whitelisted IP addresses pose security threats to Alibaba Cloud users or are used to commit law violations or patent infringements, the applicant bears full liability for the resulting impact and must compensate Alibaba Cloud for any losses.
  • Contact information (telephone number is recommended).
  • The applicant’s corporate seal.

The applicant must send the electronic copy of the company’s business license and the official letter by email to the following addresses:

  • To: dachao.xdc@alibaba-inc.com
  • Cc: yemin.ym@alibaba-inc.com
