 On an IPv4 network it is possible to find out what hosts are on a network by queering the local dynamic host configuration protocol (DHCP) server for IP leases, or since the IP Address space is so small simply scanning the network for all addresses is feasible. With IPv6 however both of these options are not available. Firstly many IPv6 networks leverage stateless address auto-configuration (SLAAC) and neighbour discovery (ND) to configure hosts without a server to maintain a list of addresses, and secondly the address space for IPv6 is huge. A standard /64 IPv6 subnet contains 18,446,744,073,709,551,61 possible addresses, this would take an enormous amount of time to scan. The solution here is to use multicast addresses.
