IPv6 (Internet Protocol version 6) is the most recent version of the Internet Protocol that was developed to replace IPv4 due to the exhaustion of available IPv4 addresses. IPv6 has several features that distinguish it from IPv4, and here are the explanations for the three features requested in the question:

  1. Autoconfiguration: One of the essential features of IPv6 is autoconfiguration, which allows devices to automatically configure their IPv6 address and other network parameters without the need for manual intervention. The autoconfiguration feature simplifies the deployment of new devices on a network and reduces the complexity of managing IP addresses manually.

  2. Optional IPsec: Another significant feature of IPv6 is the optional use of IPsec (Internet Protocol Security) for secure communication between network devices. IPv6 supports IPsec natively, whereas in IPv4, IPsec is an optional protocol that requires additional configuration. IPsec can provide confidentiality, authentication, and integrity of data traffic over the network.

  3. No Broadcasts: IPv6 has eliminated the use of broadcast addresses, which were frequently used in IPv4. In IPv6, the multicast feature is used instead of broadcast. Multicast allows a single packet to be sent to multiple devices that have subscribed to a particular group address. This feature significantly reduces the amount of network traffic and overhead, making IPv6 more efficient than IPv4.

Therefore, the correct options for the features of IPv6 protocol are:

  • C. Autoconfiguration
  • B. Optional IPsec
  • F. No Broadcasts
