Network MACMonitor WMI Provider 1.0

Network MACMonitor WMI Provider, by Apanasionak Sviataslau, is a lightweight Windows Management Instrumentation (WMI) provider that exposes network interface MAC address information and changes to standard WMI consumers. It enables administrators and monitoring tools to query current MAC addresses, observe updates across physical and virtual adapters, and subscribe to notifications when MAC-related events occur—without packet capture or intrusive drivers.

By surfacing MAC data through WMI, the provider integrates cleanly with existing management workflows, including PowerShell, Group Policy scripts, inventory systems, and SIEM platforms. It helps teams improve asset visibility, detect unauthorized changes, and maintain accurate records of network adapter states across Windows endpoints and servers.

Key capabilities:

• Real-time monitoring of MAC address presence and changes
• WMI-based data access and event subscriptions for easy automation
• Low overhead, service-style operation designed for reliability
• Compatible with both physical and virtual network adapters
• Centralized logging and auditing via standard Windows tooling

Common use cases:

• Asset inventory and hardware lifecycle tracking (e.g., NIC swaps or virtualization changes)
• Security monitoring for unauthorized adapters or potential MAC spoofing
• Troubleshooting DHCP conflicts and address assignment issues
• Compliance reporting and change management documentation

Notes:

• Designed for Windows environments using standard WMI infrastructure
• Installation and access can be governed by existing WMI namespace and system security policies
