AWS directconnect documentation change

Service: directconnect · 2025-08-22 · Documentation low

File: directconnect/latest/UserGuide/devtest-resiliency-set-up.md

Summary

Updated ASN range documentation to include long ASN support (1-4294967294), added reference to Long ASN support guide, and modified section headers

Security assessment

The changes expand documentation for valid ASN ranges and add references to long ASN support. This appears to be a feature documentation update rather than addressing a security vulnerability. No security advisories or vulnerability mitigations are mentioned.
