        **What is Subnetting IPv6?**

        Subnetting IPv6 is the process of dividing a large IPv6 network into smaller subnetworks to improve organization, routing efficiency, and address management.

        **Why is Subnetting IPv6 useful?**

        It allows efficient use of the vast IPv6 address space, simplifies network management, and enables hierarchical routing to improve scalability and performance.

        **How it works?**

        IPv6 addresses are 128 bits long; subnetting divides the address space by borrowing bits from the interface identifier portion, usually using a subnet prefix length longer than /64.

        **Where is Subnetting IPv6 used?**

        It is used in enterprise networks, ISPs, data centers, and anywhere IPv6 is deployed for organizing and managing network segments.

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

        Subnetting IPv6 operates at the Network Layer (Layer 3), dealing with IP addressing and routing.

        **Is Subnetting IPv6 Windows specific?**

        No, IPv6 subnetting is not Windows specific. It is supported by all major operating systems that support IPv6.

        **Is Subnetting IPv6 Linux specific?**

        No, IPv6 subnetting is not Linux specific. It is implemented universally wherever IPv6 is used.

        **Which Transport Protocol is used by Subnetting IPv6?**

        Subnetting IPv6 is not tied to any transport protocol. It supports all IPv6-compatible transport protocols like TCP and UDP.

        **Which Port is used by Subnetting IPv6?**

        Subnetting does not use any specific port since it is a method of address allocation and network design, not an application or service.

        **Is Subnetting IPv6 using client-server model?**

        No, subnetting is a network addressing scheme and does not involve a client-server communication model.
