224.0.0.5 - AllSPFRouters: Used to send OSPF messages to all
OSPF routers on the same network. The AllSPFRouters address
is used for Hello packets. The DR and BDR use this address
to send Link State Update and Link State Acknowledgment packets.
224.0.0.6 - AllDRouters: Used to send OSPF messages to all
OSPF DRs (the DR and the BDR) on the same network. All OSPF
routers except the DR use this address when sending Link
State Update and Link State Acknowledgment packets to the DR
