IEEE 802 NUMBERS OF INTEREST Some of the networks of all classes are IEEE 802 Networks. These systems may use a Link Service Access Point (LSAP) field in much the same way the MILNET uses the "link" field. Further, there is an extension of the LSAP header called the Sub-Network Access Protocol (SNAP). The IEEE likes to describe numbers in binary in bit transmission order, which is the opposite of the big-endian order used throughout the Internet protocol documentation.

ETHER TYPES
Many of the networks of all classes are Ethernets (10Mb) or
Experimental Ethernets (3Mb). These systems use a message "type"
field in much the same way the ARPANET uses the "link" field.

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

Multicast Bit 0 = Internet Multicast
1 = Assigned by IANA for other uses
The latter representation corresponds to the Internet standard
bit-order, and is the format that most programmers have to deal with.
Using this representation, the range of Internet Multicast addresses
is:
01-00-5E-00-00-00 to 01-00-5E-7F-FF-FF in hex, or
1.0.94.0.0.0 to 1.0.94.127.255.255 in dotted decimal
ETHERNET VENDOR ADDRESS COMPONENTS
Ethernet hardware addresses are 48 bits, expressed as 12 hexadecimal
digits (0-9, plus A-F, capitalized). These 12 hex digits consist of
the first/left 6 digits (which should match the vendor of the Ethernet
interface within the station) and the last/right 6 digits which
specify the interface serial number for that interface vendor.
Ethernet addresses might be written unhyphenated (e.g., 123456789ABC),
or with one hyphen (e.g., 123456-789ABC), but should be written
hyphenated by octets (e.g., 12-34-56-78-9A-BC).
These addresses are physical station addresses, not multicast nor
broadcast, so the second hex digit (reading from the left) will be
even, not odd.
At present, it is not clear how the IEEE assigns Ethernet block
addresses. Whether in blocks of 2**24 or 2**25, and whether
multicasts are assigned with that block or separately. A portion of
the vendor block address is reportedly assigned serially, with the
other portion intentionally assigned randomly. If there is a global
algorithm for which addresses are designated to be physical (in a
chipset) versus logical (assigned in software), or globally-assigned
versus locally-assigned addresses, some of the known addresses do not
follow the scheme (e.g., AA0003; 02xxxx).

ETHERNET MULTICAST ADDRESSES
An Ethernet multicast address consists of the multicast bit, the
23-bit vendor component, and the 24-bit group identifier assigned by
the vendor. For example, DEC is assigned the vendor component
08-00-2B, so multicast addresses assigned by DEC have the first
24-bits 09-00-2B (since the multicast bit is the low-order bit of the
first byte, which is "the first bit on the wire").

MILNET LINK NUMBERS The word "link" here refers to a field in the original MILNET Host/IMP interface leader. The link was originally defined as an 8-bit field. Later specifications defined this field as the "message-id" with a length of 12 bits. The name link now refers to the high order 8 bits of this 12-bit message-id field. The Host/IMP interface is defined in BBN Report 1822 [BBN1822]. The low-order 4 bits of the message-id field are called the sub-link. Unless explicitly specified otherwise for a particular protocol, there is no sender to receiver significance to the sub-link. The sender may use the sub-link in any way he chooses (it is returned in the RFNM by the destination IMP), the receiver should ignore the sub-link.

MILNET X.25 ADDRESS MAPPINGS
All MILNET hosts are assigned addresses by the Defense Data Network
(DDN). The address of a MILNET host may be obtained from the Network
Information Center (NIC), represented as an ASCII text string in what
is called "host table format". This section describes the process by
which MILNET X.25 addresses may be derived from addresses in the NIC
host table format.
A NIC host table address consists of the ASCII text string
representations of four decimal numbers separated by periods,
corresponding to the four octeted of a thirty-two bit Internet
address. The four decimal numbers are referred to in this section as
"n", "h' "l", and "i". Thus, a host table address may be represented
as: "n.h.l.i". Each of these four numbers will have either one, two,
or three decimal digits and will never have a value greater than 255.
For example, in the host table, address: "10.2.0.124", n=10, h=2, l=0,
and i=124. To convert a host table address to a MILNET X.25 address:
1. If h < 64, the host table address corresponds to the X.25
physical address:
ZZZZ F IIIHHZZ (SS)
where:
ZZZZ = 0000 as required
F = 0 because the address is a physical address;
III is a three decimal digit respresentation of
"i", right-adjusted and padded with leading
zeros if required;
HH is a two decimal digit representation of "h",
right-adjusted and padded with leading zeros
if required;
ZZ = 00 and
(SS) is optional
In the example given above, the host table address 10.2.0.124
corresponds to the X.25 physical address 000001240200.
2. If h > 64 or h = 64, the host table address corresponds to the
X.25 logical address
ZZZZ F RRRRRZZ (SS)
where:
ZZZZ = 0000 as required
F = 1 because the address is a logical address;
RRRRR is a five decimal digit representation of
the result "r" of the calculation
r = h * 256 + i
(Note that the decimal representation of
"r" will always require five digits);
ZZ = 00 and
(SS) is optional
Thus, the host table address 10.83.0.207 corresponds to the X.25
logical address 000012145500.
In both cases, the "n" and "l" fields of the host table address are
not used.
