This documentation is a draft for private preview for regions in the AWS European Sovereign Cloud. Documentation content will continue to evolve. Published: December 31, 2025.

RateLimitAsn

Specifies an Autonomous System Number (ASN) derived from the request's originating or forwarded IP address as an aggregate key for a rate-based rule. Each distinct ASN contributes to the aggregation instance. If you use a single ASN as your custom key, then each ASN fully defines an aggregation instance.
