What is Network Driver Interface Specification (NDIS)?
Learn about Network Driver Interface Specification (NDIS) and how it defines the functions for network adapter drivers to work with a network protocol stack.

Direct answer
- NDIS continues to evolve as the Windows network driver architecture, with the most recent public guidance focusing on newer driver models and the NetAdapterCx framework introduced around Windows 10 2004, which modernizes driver development and enables better runtime reconfiguration and offloads.[2]
Key points about recent developments
- NetAdapterCx: Since Windows 10 2004, Microsoft introduced a new driver framework called NetAdapterCx to simplify development of network adapters and to support modern features and stability improvements.[2]
- NDIS 6.x lineage: The current mainstream support tracks NDIS 6.0 and newer, with incremental updates that add capabilities such as enhanced NET_BUFFER handling, runtime reconfiguration, and support for advanced offloads across Windows versions from Vista onward to the latest Windows releases.[3][2]
- Version mappings: Public reference pages list NDIS 6.30, 6.40, 6.50, 6.51, 6.60, and later revisions tied to Windows 8.x, Windows 10, Windows 11, and corresponding server editions, indicating continued maintenance and feature expansion for current OS families.[1][3]
- Developer resources: Microsoft’s Network Driver Design Guide and Windows Driver Kit (WDK) samples remain the primary sources for implementing and testing NDIS-based or NetAdapterCx-based drivers, including guidance on NET_BUFFER, packet coalescing, and runtime reconfiguration.[2]
Illustrative takeaways
- For modern Windows driver development, expect to work with NetAdapterCx for newer adapters while maintaining compatibility with NDIS 6.x interfaces for older protocol stacks, enabling flexible driver chains and better performance hooks.[2]
- If you’re evaluating updates for a Windows server or desktop deployment, focus on the OS version’s NDIS support level (e.g., NDIS 6.60+ on newer Windows Server and Windows 10/11 builds) to determine feature availability and required driver model adjustments.[1][3]
