IPv4 had two kinds of broadcast: - all 1's (like IPv6 all-nodes link local) - subnet-directed, which RFC2644 turned into a subset of all 1's on a link IPv6 has the following kinds of multicast that are effectively broadcast: - all-nodes link-local (like IPv4 all 1's) - all-nodes site-local (arguably similar to subnet-directed, but un-doing the one-hop restriction of RFC2644) - all the multicast addresses that work over other scopes, limited only by function e.g., NTP can be "broadcast" everywhere And, depending on implementation, IPv6 anycast might use broadcast too. So IPv6 didn't remove any of IPv4's broadcast; it just gave alternatives that may or may not be used - some of which can "broadcast" even wider. Joe
