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

# MITnet addresses begin with "18" and have a 16-bit netmask.

# gateway address.
