TCP OPTION NUMBERS

The Transmission Control Protocol (TCP) has provision for optional
header fields identified by an option kind field.  Options 0 and 1 are
exactly one octet which is their kind field.  All other options have
their one octet kind field, followed by a one octet length field,
followed by length-2 octets of option data.

TELNET OPTIONS

The Telnet Protocol has a number of options that may be negotiated.
These options are listed here.  "Internet Official Protocol Standards"
(STD 1) provides more detailed information.

parameters.  These are documented in [RFC1034] and [RFC1035].  The
CLASS parameter is listed here.  The per CLASS parameters are defined
in separate RFCs as indicated.

MAIL SYSTEM NAMES


In some places, an identification of other mail systems is used.

One of these is in "The COSINE and Internet X.500 Schema" (section
9.3.18) [RFC1274].  The mail system names listed here are used as the
legal values in that schema under the "otherMailbox" attribute
"mailboxType" type (which must be a PrintableString).

Another place is in "Mapping between X.400(1988) / ISO 10021 and RFC
822" (section 4.2.2) [RFC1327].  The names listed here are used as
ToP   noToC   RFC1700 - Page 85
the legal values in that schema under the "std-or-address" attribute
"registered-dd-type" type (which must be a "key-string").

Note that key-string = <a-z, A-Z, 0-9, and "-" >.

MAIL TRANSMISSION TYPES


The Simple Mail Transfer Protocol [RFC821] and the Standard for the
Format of ARPA Internet Text Messages [RFC822] specify that a set of
"Received" lines will be prepended to the headers of electronic mail
messages as they are transported through the Internet.  These received
line may optionally include either or both a "via" phrase and/or a
"with" phrase.  The legal values for the phrases are listed here.  The
via phrase is intended to indicate the link or physical medium over
which the message was transferred.  The with phrase is intended to
indicate the protocol or logical process that was used to transfer the
message.

BOOTP AND DHCP PARAMETERS

The Bootstrap Protocol (BOOTP) [RFC951] 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 Dynamic
Host Configuration Protocol (DHCP) [RFC1531] provides a framework for
automatic configuration of IP hosts.  The "DHCP Options and BOOTP
Vendor Information Extensions" [RFC1533] describes the additions to the
Bootstrap Protocol (BOOTP) which can also be used as options with the
Dynamic Host Configuration Protocol (DHCP).

BOOTP Vendor Extensions and DHCP Options are listed below:

FOOBAR AF NUMBERS


In the FTP Operation Over Big Address Records (FOOBAR) Protocol
[RFC1639] there is a field, called "address family" or "af", to
identify the lower level protocol addresses in use.  This is an 8 bit
field.  The first 16 assignments (0-15) of the af value are exactly
the same as the IP Version number.  The assignment for values 16-255
are listed here.

DIRECTORY SYSTEM NAMES


In the representation of distinquished names (and possibly other
contexts) of the X.500 Directory system, several unique keywords may
be necessary.  For example, in the string representation of
distinguished names [RFC1485].
