AWS vpc documentation change
Summary
Updated valid IPv6 ULA range specifications from fd00::/8 to /9-/60 starting with fd80::/9
Security assessment
Clarifies CIDR range requirements but does not explicitly address a security vulnerability. The change appears to correct documentation accuracy rather than mitigate a security risk.
