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).|
