Multicast Addresses
Chapter 112
Multicast Addresses
DHCPv6 2.001 uses the following multicast addresses:
• All DHCP Agents address – FF02::1:2
DHCP clients use this link-scoped multicast address to communicate
with the on-link agent. All agents within the same DHCP domain
belong to this multicast group.
• All DHCP Servers address – FF05::1:3
DHCP clients or relays use this site-scoped multicast address to
communicate with servers in one of the following scenarios:
— When they need to send messages to all servers.
— When they do not know the server’s unicast address.
All servers within the site belong to this multicast group.
See HP-UX IPv6 Porting Guide, available at
http://docs.hp.com/hpux/netcom/index.html#IPv6, for more
information about link-local and site-local addresses.
