IANA ETHERNET ADDRESS BLOCK

The IANA owns an Ethernet address block which may be used for

multicast address asignments or other special purposes.

The address block in IEEE binary is: 0000 0000 0000 0000 0111 1010

In the normal Internet dotted decimal notation this is 0.0.94 since

the bytes are transmitted higher order first and bits within bytes are

transmitted lower order first (see "Data Notation" in the

Introduction).

IEEE CSMA/CD and Token Bus bit transmission order: 00 00 5E

IEEE Token Ring bit transmission order: 00 00 7A

Appearance on the wire (bits transmitted from left to right):

0 23 47

| | |

1000 0000 0000 0000 0111 1010 xxxx xxx0 xxxx xxxx xxxx xxxx

Multicast Bit 0 = Internet Multicast

1 = Assigned by IANA for

other uses

Appearance in memory (bits transmitted right-to-left within octets,

octets transmitted left-to-right):
