Attached are the latest network maps -- geographic and logical -- and
a list of Hosts connected to the ARPANET.
The geographic map shows all IMPs and TIPs currently installed in the
The logical map diagrams the current (as of Dec. 10, 1973) status of
all computers on the net, with the exception of MIT-MULTICS which is
shown in the advanced state of being attached to IMP #44 rather than
IMP #5. (My apologies for not reprinting the map.) Hosts with
interfaces to the subnet are shown with intersected ovals; the small
"v" represents a Very Distant Host (VDH) interface to the IMP; IMPs
are the solid black circles and TIPs the circles with "T" enclosed.
The two jagged lines represent satellite links.
Note: The names listed on this map are unofficial IMP names, NOT
official Host names.
The list of Hosts includes current sites as well as those projected
to come onto the net within the next two months. At the end is an
incomplete list of installations to be connected further in the
future. Dates for connection have been included only for the next
few months to prevent gross inaccuracy.
The Host's network address is given in octal and decimal.
Interfaces from the subnet to the particular computer are listed
in parentheses and may be ignored.
A site is considered a Server or User of the network based on
self-proclamation. Limited Server implies the site performs
service functions but for a restricted group of users dedicated
Servers implies the type of service is restricted, not the user
group. In all cases normal site access restrictions are observed.
Included in the status column is any special operating system
available for that Host, that is not supplied by the computer
This RFC contains official Host names as of December, 1973. Naming
conventions and an official Hostname list, which will be maintained
at the NIC by Jake Feinler (FEINLER@NIC), will be published in the
ARPANEWS. A version of this list will be available online at the
NIC, the location to be announced with the official Hostname list.
(Other sites are encouraged to make copies of this list available on
their own systems.) In addition, a printed version will be issued
periodically as part of the Resource Notebook
