ANSWER=There are [TE?????WTE] bits used for mapping a multicast IP address to a multicast MAC address.
REACTION_CORRECT=The MAC frame has standard prefix of 24 bits. This leaves another 24 bits for use in creating the multicast MAC address. When the MAC address is generated, the 25th bits (or high order bit) is set to 0 and then the last 23 bits of the IP address are mapped in to the remaining 23 bits of the MAC address.
