3# This file specifies the netmasks for each network supported by the
4# Athena environment.  The format for lines in the file is:
5#
6#       address         significant-bits        netmask-bits    [gateway]
7#
8# The number of netmask bits for a given IP address is the value of
9# <netmask-bits> on the first line for which <address> matches the
10# first <significant-bits> bits of the given address.  If a gateway
11# is not given, the gateway is assumed to be one greater than the
12# network address.
13#
14# The contents of this file are maintained by Athena release
15# engineering.  If you edit this file on your workstation, it will be
16# replaced at the next update and your changes will be lost.  If you
17# have local changes to make, create or add to
18# /etc/athena/masks.local, which has the same file format as this
19# file.  Entries in /etc/athena/masks.local take precedence over
20# entries in this file.
21#
22# The shell script /etc/athena/netparams uses this file to compute the
23# network, broadcast, and gateway address for a given IP address.  See
24# the comments at the top of that file for usage information.

26# Most MITnet addresses begin with "18" and have a 16-bit netmask.
27# 18.7 is being used in IS machine rooms with a 24-bit netmask.
28# At least parts of 18.7.1 are being used as /30s for servers that
29# don't like to have their IP address changed.
30# Bits of LCS also have a 24-bit netmask, according to
31# wollman@lcs.mit.edu, 1/12/98.
32# 18.101 is being used for IS internal experiments, with a 28 bit netmask.
