Many IPv6 multicast addresses are well-known to software implementing IPv6, to simplify common routing needs:

ff02::1	All nodes.
ff02::2	All routers.
ff02::5	All OSPF (Open Shortest Path First) routers.
ff02::6	All OSPF DRs (OSPF Designated Routers).
ff02::9	All RIP (Routing Information Protocol) routers.
ff02::a	All EIGRP (Enhanced Interior Gateway Routing Protocol) routers.
ff02::d	All PIM (Protocol Independent Multicast) routers.
ff02::f	UPNP (Universal Plug and Play) devices.
ff02::11	All homenet nodes.
ff02::12	VRRP (Virtual Router Redundancy Protocol).
ff02::16	All MLDv2-capable routers.
ff02::1a	All RPL (Routing Protocol for Low-Power and Lossy Networks) routers (used in Internet of Things (IoT) devices).
ff02::fb	Multicast DNS IPv6.
ff02::101	Network time (NTP).
ff02::1:2	All DHCP agents.
ff02::1:3	LLMNR (Link-Local Multicast Name Resolution).
ff02:0:0:0:0:1:ff00::/104	Solicited node address.
ff02:0:0:0:0:1-2:ff00::/104	Node information query.
ff05::1:3	All DHCP server (site).
ff05::101	All NTP server (site).
