AWS directoryservice documentation change

Service: directoryservice · 2026-06-16 · Documentation low

File: directoryservice/latest/devguide/API_AddIpRoutes.md

Summary

Updated security group rules to include IPv6 CIDR ranges alongside existing IPv4 CIDR ranges for inbound/outbound traffic

Security assessment

The changes document IPv6 support in security group rules but don't address any specific vulnerability. This enhances documentation of network security controls without patching weaknesses.
