Why Are Backend Servers Frequently Accessed by IP Addresses in 100.125.0.0/16 or 214.0.0.0/8?

Shared load balancers use IP addresses in 100.125.0.0/16 as source addresses to route traffic to backend servers and to check the health of backend servers, if you have configured a health check.

To ensure that your shared load balancer can provide services properly, ensure that the security groups configured for the backend servers allow traffic from 100.125.0.0/16.

If 100.125.0.0/16 has no available IP addresses in the region where the shared load balancer works, an IP address 214.0.0.0/8 will be used as a source IP address to forward traffic to backend servers and to check the health of backend servers.
