; -*- Fundamental -*- ; ; This file defines network and subnet data for MIT. This used to be ; just a set of comments in the host table, but things have gotten ; complicated enough that having the data be machine-readable seems ; useful. ; ; Syntax of this file is similar to HOSTS.TXT (RFC810 et al). ; ; The following keywords are defined for this file: ; NETMSK Defines the subnet mask for a network number. ; SUBNET Allocates a subnet number. ; RESERV Reserves a subnet number; like SUBNET but indicates ; that the subnet number is not necessarily in use. ; UNUSED Indicates free subnet number; data portion, if any, ; refers to the last known user of this subnet number. ; BROKEN Like SUBNET but indicates that there is a known ; conflict between this subnet allocation and another ; subnet allocation (which should also be flagged with ; BROKEN). ; ; Obviously, noone should ever allocate a BROKEN subnet, the keyword ; exists solely to inform consistancy-checking code that there is a ; known problem with this subnet. ; ; ; MIT Network numbers and subnet masks. Not all of these networks are ; in actual use. The entry for chaosnet has nothing to do with any ; existing network implementation, it's just to provide a way to write ; the dotted-decimal form of a subnet address for a chaos-only wire. ; Also note that current MIT usage can't handle a class-C net, so ; MIT-TEST can never be part of the current MIT subnetting scheme. ; ; Net number Net name Subnet mask NETMSK : 0.0.0.0 : CHAOSNET : 000.000.255.000 : NETMSK : 18.0.0.0 : MIT-TEMP : 255.255.000.000 : NETMSK : 128.30.0.0 : MIT-NET : 255.255.255.000 : NETMSK : 128.31.0.0 : MIT-RES : 255.255.255.000 : NETMSK : 128.52.0.0 : MIT-AI-NET : 255.255.255.000 : ;xxxxx : 192.12.11.0 : MIT-TEST : 255.255.255.000 : ; ; ; MIT subnet numbers. ; ; Only 0172 subnets will fit in a Chaos routing packet. ; Subnets 0172 and above should be used for IP only subnets. ; ; Nets marked with a * are where the subnets are different in IP and ; CHAOS due to brain bubbles in octal->decimal conversion when putting ; in Athena nets. ; ; Octal IP-decimal Authority Explanation RESERV : 0 : 0.0.0.0 : MIT.EDU : Not to be used SUBNET : 01 : 0.0.1.0 : MIT.EDU : Main campus Chaosnet SUBNET : 02 : 18.2.0.0 : LCS.MIT.EDU : Tech Square 3MB Ethernet SUBNET : 03 : 0.0.3.0 : LCS.MIT.EDU : MX IO 11 pseudo net SUBNET : 04 : 0.0.4.0 : AI.MIT.EDU : AI CHAOS 11 pseudo net SUBNET : 05 : 0.0.5.0 : LCS.MIT.EDU : XX NETWORK 11 pseudo net SUBNET : 06 : 0.0.6.0 : MIT.EDU : Tech Square Chaosnet SUBNET : 07 : 0.0.7.0 : MIT.EDU : PFC link SUBNET : 010 : 0.0.8.0 : LCS.MIT.EDU : LCS 2nd-3rd floor Chaosnet SUBNET : 011 : 18.9.0.0 : LCS.MIT.EDU : Tech Square LCS asynchronous line net SUBNET : 012 : 18.10.0.0 : LCS.MIT.EDU : Tech Square Pronet SUBNET : 013 : 0.0.11.0 : MIT.EDU : EE NETWORK 11 pseudo net RESERV : 014 : 18.12.0.0 : MIT.EDU : Reserved (ask JNC) SUBNET : 015 : 0.0.13.0 : MIT.EDU : Building 26 Ethernet (Infinite to Electronic Music Studio) SUBNET : 016 : 128.52.14.0 : AI.MIT.EDU : AI Lab Ethernet 16 SUBNET : 017 : 0.0.15.0 : MIT.EDU : West Campus Chaosnet (Math Dept, ...)
