For broadcasting, IPv6 uses a special broadcast address, unlike IPv4, where the original host address is broadcasted. True or false?
True
False
Go to: http://ipv6friday.org/blog/2011/12/ipv6-multicast to learn the WHOLE DEAL. Here is a snapshot:
In IPv6, there’s no longer any broadcast – There’s only multicast, unicast and anycast. In IPv6 all nodes are required to support multicast. Without multicast, many services that you need will simply not work. There’s a constant hum from the network on the multicast channels.
IPv6 is a new protocol and had multicast services from start, so network discovery functions now builds upon multicast instead. This means that hosts that run these servers listen to the multicast addresses and other hosts will not be bothered when a client sends IP packets to these addresses. Multicast also enables site-wide and global services where clients subscribe to a data stream. To quote RFC 4291:
Multicast: An identifier for a set of interfaces (typically belonging to different nodes). A packet sent to a multicast address is delivered to all interfaces identified by that address.
There are no broadcast addresses in IPv6, their function being superseded by multicast addresses.
