In IPv6, which of the following addresses is used for

Solution

A Link-local address in IPv6 is used for communication between nodes on the same link (local network segment) and is not routable beyond that network. These addresses are automatically assigned to each network interface and can be used for tasks like neighbor discovery and auto-configuration. Option A (Global Unicast Address): A Global Unicast Address (GUA) is a routable IPv6 address that can be routed across the internet, so it is not restricted to the local network. Option C (Multicast Address): A Multicast Address is used to send data to multiple devices on a network, but it is not restricted to local communication and can be routed across networks. Option D (Anycast Address): An Anycast Address is assigned to multiple interfaces, with packets sent to the nearest one, but it is not limited to the local network. Option E (Broadcast Address): IPv6 does not use Broadcast addressing; it uses Multicast and Anycast for similar functionalities. Therefore, this option is incorrect.
