RFC 1060
Assigned numbers
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 (which is in bit transmission
order):
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):
0 23 47
| | |
0000 0001 0000 0000 0101 1110 0xxx xxxx xxxx xxxx xxxx xxxx
| |
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
IP TOS PARAMETERS
This documents the default Type-of-Service values that are currently
recommended for the most important Internet protocols.
There are three binary TOS attributes: low delay, high throughput,
and high reliability; in each case, an attribute bit is turned on to
indicate "better". The three attributes cannot all be optimized
simultanously, and in fact the TOS algorithms that have been
discussed tend to make "better" values of the attributes mutually
exclusive. Therefore, the recommended values have at most one bit
on.
Generally, protocols which are involved in direct interaction with a
human should select low delay, while data transfers which may involve
large blocks of data are need high throughput. Finally, high
reliability is most important for datagram-based Internet management
functions.
Application protocols not included in these tables should be able to
make appropriate choice of low delay (1 0 0) or high throughput (0 1
0).
The following are recommended values for TOS:
----- Type-of-Service Value -----
Low High High
Protocol Delay Throughput Reliability
TELNET (1) 1 0 0
FTP
Control 1 0 0
Data (2) 0 1 0
TFTP 1 0 0
SMTP (3)
Cmd phase 1 0 0
DATA phase 0 1 0

BOOTP 0 0 0
Notes:
(1) Includes all interactive user protocols (e.g., rlogin).
(2) Includes all bulk data transfer protocols (e.g., rcp).
(3) If the implementation does not support changing the TOS
during the lifetime of the connection, then the recommended
TOS on opening the connection is (0,0,0).
IP TIME TO LIVE PARAMETER
The current recommended default TTL for the Internet Protocol (IP)
RFC-791 [45,105] is 32.
DOMAIN SYSTEM PARAMETERS
The Internet Domain Naming System (DOMAIN) includes several
parameters. These are documented in RFC-1034, [81] and RFC-1035
[82]. The CLASS parameter is listed here. The per CLASS parameters
are defined in separate RFCs as indicated.

BOOTP PARAMETERS
The Bootstrap Protocol (BOOTP) RFC-951 [36] describes an IP/UDP
bootstrap protocol (BOOTP) which allows a diskless client machine to
discover its own IP address, the address of a server host, and the
name of a file to be loaded into memory and executed. The BOOTP
Vendor Information Extensions RFC-1084 [117] proposes an addition to
the Bootstrap Protocol (BOOTP).
Vendor Extensions are listed below:

NETWORK MANAGEMENT PARAMETERS
For the management of hosts and gateways on the Internet a data
structure for the information has been defined. This data structure
should be used with any of several possible management protocols, such
as the "Simple Network Management Protocol" (SNMP) RFC-1098 [15], or
the "Common Management Information Protocol over TCP" (CMOT) [142].
The data structure is the "Structure and Indentification of Management
Information for TCP/IP-based Internets" (SMI) RFC-1065 [120], and the
"Management Information Base for Network Management of TCP/IP-based
Internets" (MIB) [121].
The SMI includes the provision for parameters or codes to indicate
experimental or private data structures. These parameter assignments
are listed here.
The older "Simple Gateway Monitoring Protocol" (SGMP) RFC-1028 [37]
also defined a data structure. The parameter assignments used with
SGMP are included here for hist orical completeness.

ARPANET AND MILNET LOGICAL ADDRESSES
The ARPANET facility for "logical addressing" is described in RFC-878
[57] and RFC-1005 [109]. A portion of the possible logical addresses
are reserved for standard uses.
There are 49,152 possible logical host addresses. Of these, 256 are
reserved for assignment to well-known functions. Assignments for
well-known functions are made by the IANA. Assignments for other
logical host addresses are made by the NIC.

ARPANET AND MILNET LINK NUMBERS
The word "link" here refers to a field in the original ARPANET
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 [2].
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.

ARPANET AND 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.
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 ARPANET 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.

At an ad hoc special session on "IEEE 802 Networks and ARP", held
during the TCP Vendors Workshop (August 1986), an approach to a
consistent way to send DoD-IP datagrams and other IP related
protocols (such as the Address Resolution Protocol (ARP)) on 802
networks was developed, using the SNAP extension (see RFC-1010 and
RFC-1042 [90]).
ETHERNET NUMBERS OF INTEREST
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.
If you need an Ethernet type, contact the Xerox Corporation, Xerox
Systems Institute, 475 Oakmead Parkway, Sunnyvale, CA 94086, Attn:
Ms. Fonda Pallone, (408) 737-4652.

The standard for transmission of IP datagrams over Ethernets and
Experimental Ethernets is specified in RFC-894 [61] and RFC-895 [91]
respectively.
NOTE: Ethernet 48-bit address blocks are assigned by the IEEE.

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).
