        **What is IPv6 Packet Routing?**

        IPv6 Packet Routing refers to the process of forwarding IPv6 packets from a source to a destination across interconnected networks using routing tables and protocols.

        **Why is IPv6 Packet Routing useful?**

        It enables efficient and scalable packet forwarding by utilizing hierarchical addressing and improved routing protocols, ensuring packets reach the correct destination.

        **How does IPv6 Packet Routing work?**

        Routers use the destination IPv6 address to determine the next hop based on routing tables and protocols such as OSPFv3, RIPng, and BGP. Routing aggregation reduces table sizes and improves performance.

        **Where is IPv6 Packet Routing used?**

        It is used in all IPv6 networks — from small enterprise LANs to large ISPs and the global Internet — to deliver data across multiple network segments.

        **Which OSI layer does IPv6 Packet Routing belong to?**

        Packet routing operates at the **Network Layer (Layer 3)** of the OSI model, responsible for logical addressing and path selection.

        **Is IPv6 Packet Routing Windows specific?**

        No, IPv6 routing is supported across all major operating systems including Windows.

        **Is IPv6 Packet Routing Linux specific?**

        No, Linux has robust support for IPv6 routing with tools like `ip -6 route` and advanced routing daemons.

        **Which Transport Protocol is used by IPv6 Packet Routing?**

        Routing works independently of transport protocols, handling all IPv6 packets regardless of whether the payload is TCP, UDP, or ICMPv6.

        **Is IPv6 Packet Routing using client-server model?**

        No, packet routing is a network-layer function that forwards packets between nodes without relying on client-server communication models.
