Features of IPv6

AC

IPv6 is the latest version of the Internet Protocol, designed to replace IPv4, which is running out of address space. IPv6 provides several new features that IPv4 doesn't have. The two features of IPv6 are:

1. Anycast: Anycast is a communication method in which a single destination address represents multiple endpoints (nodes). When a packet is sent to an anycast address, it is delivered to the closest endpoint based on the network topology. Anycast is useful for load balancing, fault tolerance, and efficient content delivery.

2. Multicast: Multicast is a communication method in which a single packet is sent to multiple destinations simultaneously. In IPv6, multicast addresses are used for communication with a group of nodes. When a node wants to join a multicast group, it sends a multicast listener report to the multicast router, which then adds the node to the multicast group. Multicast is useful for multimedia streaming, online gaming, and other applications that require group communication.

The other options in the question, broadcast, podcast, and allcast, are not features of IPv6:

• Broadcast is a communication method in which a packet is sent to all nodes on the network. IPv6 doesn't support broadcast, but it provides multicast as an alternative.
• Podcast is a term used for distributing digital media files (audio or video) over the internet, and it's not a feature of IPv6.
• Allcast is not a recognized term in the context of networking or IPv6.
