WebMay 22, 2012 · You can read more about how multicast IP addresses map to multicast ethernet addresses at various sites. The Wikipedia article is about as good as it gets: The IANA owns the OUI MAC address 01:00:5e, therefore multicast packets are delivered by using the Ethernet MAC address range 01:00:5e:00:00:00 - 01:00:5e:7f:ff:ff. This is 23 … WebJan 1, 2010 · For example, ether[0] & 1 != 0 catches all multicast traffic. The &-sign means bit-wise masking, so the above expression basically checks the first byte’s last bit 1. The expression ip[0] & 0xf != 5 catches all IPv4 packets with options.

WebIn order to avoid a kind of multicast ARP to map multicast IP addresses to ethernet/FDDI ones, the IANA reserved a range of addresses for multicast: every ethernet/FDDI frame with its destination in the range 01-00-5e-00-00-00 to 01-00-5e-ff-ff-ff (hex) contains data for a multicast group. The prefix 01-00-5e identifies the frame as multicast ...
