        **What is IPFIX?**

        IPFIX (IP Flow Information Export) is a protocol for exporting flow information from routers, switches, and other network devices to a collector for analysis, monitoring, and billing. It is standardized by the IETF as an evolution of Cisco’s NetFlow v9.

        **Why is IPFIX useful?**

        IPFIX is useful for network monitoring, traffic analysis, intrusion detection, usage-based billing, and capacity planning. It provides detailed information about traffic flows in a standardized format.

        **How it works?**

        IPFIX-enabled devices generate flow records based on observed network traffic. These records are exported to a collector using a predefined or custom template. The collector then processes and analyzes the flow data for visibility or action.

        **Where is IPFIX used?**

        IPFIX is widely used by ISPs, data centers, and enterprises in network operations centers (NOCs) for monitoring, analytics, performance management, and security.

        **Which OSI layer does this protocol belong to?**

        IPFIX operates at the Application Layer (Layer 7), as it defines how flow data is exported and formatted for external use.

        **Is IPFIX Windows specific?**

        No, IPFIX is not Windows specific. While collectors or exporters may run on Windows, the protocol itself is platform-independent and used on a wide range of network devices.

        **Is IPFIX Linux specific?**

        No, IPFIX is not Linux specific. Many open-source and commercial IPFIX collectors run on Linux, but the protocol is also supported across other platforms and network hardware.

        **Which Transport Protocol is used by IPFIX?**

        IPFIX can use **UDP**, **TCP**, or **SCTP** as its transport protocol. UDP is the most common due to its lower overhead, but TCP/SCTP may be used where reliability is needed.

        **Which Port is used by IPFIX?**

        IPFIX commonly uses **UDP port 4739**, though other ports can be configured depending on the implementation.

        **Is IPFIX using client-server model?**

        Yes, IPFIX follows a client-server-like model where the **exporter (client)** sends flow data to the **collector (server)** for storage and analysis.
