RFC 752
Universal host table
A Universal Host Table 🎀
Okay bestie, here's the title block 💖. This is RFC 752, called A Universal Host Table. It was written by Mark Crispin at SU-AI (the NIC number is nnnnn), for the Network Working Group, and it's dated 2 January 1979 🦋. The header doesn't list a category, and it doesn't obsolete or update anything, so no drama there ✨.
ABSTRACT ✨
This doc describes the network host table that MIT and Stanford use 🌸. It's way better than the NIC host table and the Tenex host table, no cap 💅. There's also a binary file that gets compiled from this host table. The subsystems on MIT's ITS and Stanford's WAITS timesharing systems read that file so their host and network lookups are fast 🔥.
HISTORY 📜
Like lots of other sites on the Arpanet, we found the NIC host table kinda unusable for our needs 💀. It was often inaccurate, and it kept missing nicknames people actually used in our communities 🙈. Its format was also awkward for user programs, especially ones that wanted the table mapped into memory as some structured binary thing for quick lookups. And honestly? The NIC table just doesn't include some essential info 😭.
The ITS host table was originally built to get compiled right into a network handling program. (MIDAS, the PDP-10 assembler, has a pseudo-op that pulls a file into an assembly.) To keep the assembler happy, every comment line started with a semicolon, and every real data line started with the word HOST. Each program that used the table defined HOST as an assembly macro before pulling the table in 🧚.
This worked for a while, but as the network grew, hosts changed status more often, and more network programs had to be reassembled every time the table changed 😩. If the right person for a subsystem wasn't around, that subsystem could sit on an old table for ages 💤.
In the spring of 1977, design started on a binary file that would live in a system directory, and every subsystem that wanted host table info could read it in 🦋. The format was carefully designed to be general enough for all the different subsystems. Every subsystem needed changes to use it, but those changes were trivial compared to not having to recompile every single subsystem 🙌.
Later, the host table and binary file were imported to the WAITS system at Stanford, where they eventually replaced the old host table 🌈. Recently, multiple network support was added, including hosts being on more than one network. A fancier compiler also replaced the assembler macros, so the program that generates the binary file now does the compiling itself ✨.
THE HOST TABLE 🌸
Quick notation check 🧠: in these descriptions, angle brackets and lower case are used as a meta-linguistic device. Spaces and tabs are often ignored and can be used freely in the source format, but commas are always explicit delimiters. A semicolon always starts a comment, and everything after it on that line gets ignored, though any text before the semicolon is still processed as usual. The syntax rules should be obvious from the host table in the appendix 📖. Names are alphanumeric strings made of A-Z, 0-9, and - (dash). Quoting is used to separate examples from the text, and it isn't part of the example.
The host table is made of commentary and two types of text lines 💜. Commentary lines start with a semicolon, and the compiler ignores them. They're there for humans who read or edit the table. Commentary can be mixed case, but text lines are traditionally all upper case. There are two kinds of text lines: host and network.
Network text lines start with the word NET followed by a space or tab. They give a network name and the network number (as assigned by Postel) for that network. There aren't any officially assigned network names yet, so the names were picked more or less from the English names in Postel's "Assigned Numbers", RFC 750 📜. These names might change later, but some software depends on the names ARPA, CHAOS, and DIAL for the ARPANET, Chaos net, and Dialnet 💅.
The format of a network text line is:
NET <name>,<decimal-number>For example, the ARPANET's entry would look something like:
NET ARPA,10Host text lines start with the word HOST followed by a space or tab. They specify a host name, a host address list, whether the host is a "user" or a "server", the name of the host's operating system, the name of the host's machine type, and a nickname list. The operating system, machine type, and/or nickname list can be left out, in which case they default to unknown or null 🌷.
The host name is a unique name string for that host. For ARPANET sites, it's the official name the NIC assigned. For other networks, it's whatever name is in common use on that network. So far, there haven't been any naming conflicts on multiple-network hosts 🙌.
The host address list is either a single host address or a list of host addresses in square brackets, separated by commas. A host address is a network name, a space, and the host's address on that network. If the network name isn't specified, it defaults to ARPA, so "ARPA 0/11" and "0/11" are equivalent 🤓. Different networks parse host addresses in different ways:
- ARPANET addresses use BBN-style host number slash IMP number notation, with both numbers in decimal. So host 2 on IMP 6 is written "2/6". Yes, it's backwards, but it's become such a network standard that people have to use it 🙃. Old-style octal addresses are allowed (e.g. "206" for "2/6"), but they're no longer used or supported.
- CHAOS net addresses are a single octal number, e.g. "CHAOS 2026", and they specify the host's address on the CHAOS net.
- Dialnet addresses are a ten-digit decimal number, and they specify the TelCo (phone) number of the host's Dialnet port 📞.
The user vs. server label is generally taken to mean "according to the NIC" for ARPANET hosts 🏷️. A server is a host where making a connection to a remote service is a meaningful operation. For some hosts with limited servers, the definition often changes from the official one, depending on the circumstances. For example, "users" who have an FTP server and occasionally a TELNET server may be called "servers". On the flip side, a "server" that doesn't accept MAIL and rejects MAIL in a pathological way (e.g. by hanging) might be labelled a "user" 💀.
The name of the host's operating system is a string, much like the host name, such as "ITS", "TOPS-20", or "MULTICS". Some subsystems use this information to predict certain behavior of the remote server. For example, a MAIL user subsystem knows that for operating system "MULTICS" it has to log in as user NETML before trying to deliver the mail 📬.
The name of the host's machine type is also a string. For the convenience of several subsystems, all DEC "PDP-n" machines are entered without the dash, and all PDP-10-like machines (e.g., KL-20, MAXC, etc.) are considered to be PDP-10s. They get entered as "PDP10", since that's a single 36-bit word in 7-bit ASCII 🧮. Like the operating system name, several subsystems use this information too. For example, a PDP-10 FTP user process will try to negotiate 36-bit image mode with another PDP-10, and a Tenex or Tops-20 site will try to negotiate paged transfers with another Tenex or Tops-20 🫶.
The nick name list is in square brackets and consists of a series of names separated by commas. There can be any number of nick names 💜.
The format of a host text line is:
HOST <name>,<address-list>,<status>,<system>,<machine>,<nickname-list>For example, an entry might look something like:
HOST MIT-AI,[ARPA 2/6,CHAOS 2026],SERVER,ITS,PDP10,[AI,MITAI]This entry describes a host named "MIT-AI" on two networks (ARPANET and CHAOS net), with ARPANET address "2/6" and CHAOS net address "2026". It's a server site running an operating system called "ITS" on "PDP10" hardware. It has two nicknames, "AI" and "MITAI" 🎀.
ADDRESS table (one per network): okay bestie, this one's giving "one table per network" energy 🦋 Here's the layout:
word 0 Number of entries in table.
word 1 Number of words per entry, currently 2.
entry word 0 Network address of this entry, including network number.
For ARPANET addresses this is in the format:
xxx000,,000000 Network number
000xxx,,xxx000 IMP number
000000,,000xxx Host number
Each number is right justified.
For CHAOS net addresses it is an octal number.
For Dialnet addresses it is the address in the file of
the TelCo number in ASCIZ.
entry word 1 Left half: Address in file of SITE table entry.
Right half: Address in file of next ADDRESS table entry
for this site (zero means end of list).SITE table: the site era is here 💅
word 0 Number of entries in table.
word 1 Number of words per entry, currently 3.
entry word 0 Left half: Address in file of official name in ASCIZ.
Right half: Address in file of first ADDRESS table entry
for this site.
entry word 1 Left half: Address in file of operating system name in
ASCIZ (zero means unknown).
Right half: Address in file of machine type in ASCIZ
(zero means unknown).
entry word 2 Left half: Flags. The 400000 bit means a server site.
Right half: reservedNAMES table: the final table, and it's giving tidy 🎀
word 0 Number of entries in table.
word 1 Number of words per entry, currently 1.
entry word 0 Left half: Address in file of SITE table entry for this
host.
Right half: Address in file of host name in ASCIZ.CONCLUSION: 🌈
okay so the wrap-up is that we built a host table that can handle the full host addressing of the ARPANET plus extra networks, and we also made a binary file format so the host table data is easy to work with ✨ It's honestly so good.
We're writing this format up so the outside world can see it as a suggested replacement for the current host table 💖 The best part is that it's already been built and it's actually in use at MIT and Stanford 🫶 We also came up with some conventions for network names, because there aren't any network names assigned yet. So this RFC is also kind of a request to get the community talking about getting names assigned to the networks, for the sake of host tables 🙈
Anybody who is interested in bringing our host table into their own system should reach out to David Moon (MOON@MIT-MC) or me (MRC@SU-AI) for more info 💅

ACKNOWLEDGEMENTS: 🫶
So many people helped design and build the current host table 🌸 In no particular order, that's Richard Stallman, David Moon, Ken Harrenstien, and Mark Crispin. I'm not going to list everyone's contributions one by one, because it's hard to tell who did what, and honestly that sort of stuff is boring to read anyway 😭
APPENDIX 🧚
The host table as of this writing is listed in this appendix 🦋
; ITS/SAIL Host Table
; Last updated: MRC 1/2/79
; Although the file <NETINFO>HOSTS.TXT at SRI-KL is the
; official NIC host table, it is occasionally delayed in
; reflecting actual network status, and does not include
; colloquial-usage nicknames, operating system names,
; machine types, or networks...
; Hence this file, which is manually updated as necessary.
; The "official" version is maintained as AI:SYSENG;HOSTS >
; and copies are kept on SYSENG;HOSTS > on the other ITS
; systems. SAIL's version is kept on HOSTS.TXT[NET,MRC].
; Modifications should be made to the AI file and a note of
; the change sent to Info-Hosts@AI and Info-Net@SAIL. If
; you're going to modify it, you should warn MRC@SAIL and
; SWG@DM, who normally maintain it, to avoid timing errors.
; The easy way to compile the binary file and install it is
; to run the batch command files:
; :XFILE SYSENG;HOSTS XFILE at AI or
; .BATCH /NOW @HOSTS.[NET,MRC] at SAIL.
; If you want to do it the hard way, read those files.
; The network table is in the format of one line entries looking like:
; NET <name>,<network #>
; sorted alphabetically by network name. All fields should be
; in upper case. The fields are:
; <name> official name of this network (whenever such
; names get assigned; currently whatever sounds
; good).
;
; The convention I have established is to
; abbreviate "packet radio network" to "-PR".
; "NET" is generally not part of the name unless
; it is a proper name. The three networks
; currently used by MIT and Stanford don't have
; "NET" in them.
Mark Crispin [page A-1]
; <network #> A single network number, in DECIMAL. These
; numbers are assigned by Jon Postel.
; The host table is in the format of one line entries looking like:
; HOST <name>,<host #s>,<status>,<system>,<machine>,[<nicknames>]
; sorted alphabetically by host name. All fields should be
; in upper case. The fields are:
; <name> official name of this site according to the
; NIC.
; <host #s> A single <host #> or a list of them in
; brackets and separated by commas, with no
; spaces in between.
;
; A <host #> is an OCTAL number, optionally
; preceded by a network name (ARPA, CHAOS, DIAL)
; and a space. The default network name if none
; is supplied is ARPA.
;
; Arpanet host numbers are represented in
; BBN's backwards host slash IMP notation with
; both numbers in DECIMAL. This gets compiled
; into the 1.1 through 1.8 bits being the host
; number, and the 2.1 through 3.7 bits being
; the IMP number. For example, MIT-AI (host 2
; on IMP 6 or 2/6) is compiled as 6002. Note
; that the 1.9 and the 3.7 through 4.9 bits are
; always zero! The HOSTS1 program compiles
; into the old style 8 bit format (1.1-1.3 for
; host number, 1.4-1.8 IMP number) whenever
; possible; HOSTS2 and future programs only use
; the new format.
;
; Chaosnet host numbers are in octal.
;
; Dialnet host "numbers" are really pointers to
; an ASCII string. In the source, they are
; represented as a 10-digit TelCo number.
; <status> whether USER or SERVER. This is usually the
; status "according to the NIC".
; <system> operating system name (e.g., TENEX, ITS,
; MULTICS, etc). Many elves actually have
; other systems behind them; if possible, the
; system behind the ELF is used rather than
; the ELF. Also, TOPS-10 is used rather than
Mark Crispin [page A-2]
; TOPS10.
; <machine> actual machine type (e.g., PDP10, 370, PDP11,
; etc). By convention, KA-10, KI-10, KL-10,
; KL-20 and MAXC are all considered to be
; PDP-10s. No - should be after "PDP"; this
; is so it fits in one 36-bit word.
; <nicknames> nick names for this host (whether NIC
; nicknames or local ones). The list is in
; square brackets and each name is delimited
; by a comma.
