Changes

To ensure service upgrade stability, the Security Center server IP address removal originally scheduled for March 5, 2026 will be postponed. The specific implementation time will be announced later.

During this period, continue using the current service endpoints. If you have configured access control policies, such as IP address whitelists or Domain Allowlists, update your security policies promptly using the following list of active IPs to ensure normal business access:

• IP addresses that provide basic communication services for agents in the Chinese mainland:

47.117.157.227

8.153.161.116

8.153.86.12

106.14.18.21

106.11.248.209 (Scheduled for removal)

106.14.104.2 (Scheduled for removal)

47.116.1.151 (Scheduled for removal)

• IP addresses that provide file download services, such as upgrades, for agents in the Chinese mainland:

106.14.97.100

8.153.93.165

139.196.179.111

8.153.199.39

106.11.250.224 (Scheduled for removal)

47.116.0.190 (Scheduled for removal)

106.15.49.85 (Scheduled for removal)

Impact scope

This delayed change affects only Security Center agents in the Chinese mainland. Assets outside the Chinese mainland are not affected.
