IPv6 is the latest version of the Internet Protocol (IP) which is designed to replace IPv4. It is intended to address the shortcomings of IPv4, such as address exhaustion and security vulnerabilities, and provide improved functionality for modern networking needs. Here are the three features of the IPv6 protocol:

  1. No Broadcasts: IPv6 does not use broadcast transmissions like IPv4 does. Instead, it uses multicast transmissions to communicate with multiple devices at once. In IPv4, broadcasts are used to send a message to all devices on the same network segment, which can lead to unnecessary traffic and security risks. With IPv6, multicast addresses are used to send messages to specific groups of devices, reducing the amount of traffic and enhancing security.

  2. Plug-and-Play: IPv6 is designed to make it easier to connect devices to a network. It has a built-in feature called "Plug-and-Play" (PnP) that allows devices to automatically configure themselves for use on a network without requiring manual intervention. With IPv6 PnP, devices can automatically obtain an IP address and other network settings, making it much easier to set up and manage a network.

  3. Optional IPsec: IPv6 includes support for Internet Protocol Security (IPsec), a set of protocols that provide secure communication over IP networks. Unlike IPv4, where IPsec is optional, IPv6 requires support for IPsec. However, it is still possible to use IPv6 without IPsec if desired, as it is an optional feature. IPsec provides enhanced security features such as encryption and authentication, which are essential for secure communication over the internet.

Therefore, the correct answers are B. Plug-and-play, C. No broadcasts, and F. Autoconfiguration.
