Which statement about IPv6 is correct?

The statement about IPv6 that is correct is that broadcast has been replaced with multicast. IPv6 is the most recent version of Internet Protocol (IP), which provides an identification and location system for computers on networks and routes traffic across the Internet. IPv6 has several improvements over IPv4, such as a larger address space, simplified header format, enhanced security, and better support for mobility and QoS.One of the changes in IPv6 is that it does not support broadcast, which is a method of sending a packet to all nodes on a network segment. Instead, IPv6 uses multicast, which is a method of sending a packet to a group of nodes that have joined a multicast address34.
