AWS AWSCloudFormation documentation change

Service: AWSCloudFormation · 2025-05-01 · Documentation low

File: AWSCloudFormation/latest/UserGuide/aws-properties-apigateway-domainnamev2-endpointconfiguration.md

Summary

Added IpAddressType property to API Gateway DomainNameV2 EndpointConfiguration, allowing specification of IPv4/dualstack IP address types for API invocations.

Security assessment

While controlling IP address types can influence network security, the change is a general configuration option without explicit ties to mitigating a security vulnerability or describing a dedicated security feature.
