Hi all, I read that ipv6 does not broadcast, in which case how does it find the other local hosts and gateway on the lan ?

Hello Carl,
this is one of the most interesting aspects in IPv6.
IPv6 has built-in multicast address support.
So all processes like neighbor discovery use ICMPv6 messages with special multicast destinations in order to:
find possible duplicated address
to find out the MAC address of a neighbor (substitutes IPv4 ARP)
see

Hope to help

hi there
can you ellaborate on this?
if it uses multicast, switches still treat this as broadcast so wont it effectivly flood the network still ?
