D.Multicast addresses 224.0.0.5 and 224.0.0.6 are source multicast addresses for OSPF routers
E.The a dministratively scoped multicast addresses 239.0.0.0 through 239.255.255.255 are similar in purpose to RFC 1918 private unicast addresses
F.Multicast address 224.0.1.1 has been reserved for the Network Time Protocol (NTP) by the IANA
