Azure Private Link over IPv6 enables you to privately access Azure PaaS services, such as Azure Storage and Azure SQL Database, over IPv6-based connectivity. You can now use IPv6 private endpoints to connect from IPv6 clients in an Azure virtual network or from on-premises networks over ExpressRoute.

Perimeter link (cross-perimeter connectivity) is a network security perimeter capability that allows trusted resources in two different network security perimeters to securely communicate with each other using Managed Identity (MSI), without requiring additional network security perimeter access rules or network configuration changes. It preserves Zero Trust boundaries while enabling controlled service-to-service access across perimeters
