                               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] describes 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-1157 [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-1155 [120], and the
   "Management Information Base for Network Management of TCP/IP-based
   Internets" (MIB-II) [121].

   The SMI includes the provision for panrameters 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.

   The network management object identifiers are under the iso (1), org
   (3), dod (6), internet (1), or 1.3.6.1, branch of the name space.

                           MILNET LOGICAL ADDRESSES

   The MILNET 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.

                             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 [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.

                         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.

Top       Page 52 
   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 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.

   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-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, (415) 813-7164.

   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).

                             PRONET 80 TYPE NUMBERS

   Below is the current list of PRONET 80 Type Numbers.  Note: a
   protocol that is on this list does not necessarily mean that there is
   any implementation of it on ProNET.

   Of these, protocols 1, 14, and 20 are the only ones that have ever
   been seen in ARP packets.

   For reference, the header is (one byte/line):

           destination hardware address
           source hardware address
           data link header version (2)
           data link header protocol number
           data link header reserved (0)
           data link header reserved (0)

   Some protocols have been known to tuck stuff in the reserved fields.

   Those who need a protocol number on ProNET-10/80 should contact John
   Shriver (jas@proteon.com).

                  POINT-TO-POINT PROTOCOL FIELD ASSIGNMENTS

PPP DLL PROTOCOL NUMBERS

   The Point-to-Point Protocol (PPP) Data Link Layer [146,147,175]
   contains a 16 bit Protocol field to identify the the encapsulated
   protocol.  The Protocol field is consistent with the ISO 3309 (HDLC)
   extension mechanism for Address fields.  All Protocols MUST be
   assigned such that the least significant bit of the most significant
   octet equals "0", and the least significant bit of the least
   significant octet equals "1".

   c223            Challenge Handshake Authentication Protocol

   Protocol field values in the "0---" to "3---" range identify the
   network-layer protocol of specific datagrams, and values in the "8--
   -" to "b---" range identify datagrams belonging to the associated
   Network Control Protocol (NCP), if any.

   It is recommended that values in the "02--" to "1e--" and "--01" to
   "--1f" ranges not be assigned, as they are compression inefficient.

   Protocol field values in the "4---" to "7---" range are used for
   protocols with low volume traffic which have no associated NCP.

   Protocol field values in the "c---" to "e---" range identify
   datagrams as Control Protocols (such as LCP).

PPP LCP AND IPCP CODES

   The Point-to-Point Protocol (PPP) Link Control Protocol (LCP) [146]
   and Internet Protocol Control Protocol (IPCP) [147] contain an 8 bit
   Code field which identifies the type of packet.  These Codes are
   assigned as follows:
