What is NOT a feature of IPv6?

In IPv6, the feature that is notably absent is support for broadcast. Instead of using broadcast for transmitting data to multiple destinations on a network, IPv6 employs multicast and anycast methods. Multicast allows a single packet to be sent to multiple destinations simultaneously, while anycast sends a packet to the nearest interface among a group of potential receivers. This distinguishes IPv6 from its predecessor, IPv4, which utilizes broadcast extensively.

The other aspects mentioned highlight major advantages of IPv6. Multi-layer addressing enables better organization of IP addresses across different layers of the networking model, promoting more efficient routing and management. Automatic address configuration allows devices on a network to self-assign IP addresses without manual intervention, facilitating easier network setup and device connectivity. Additionally, the increased address space of IPv6—boasting a vastly larger number of available IP addresses compared to IPv4—addresses the growing demand for IP addresses due to the proliferation of internet-connected devices.
