| 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 | # |

|---|
| 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 |
|---|

|---|
| 18 | # /etc/athena/masks.local, which has the same file format as this |
|---|

| 22 | # The shell script /etc/athena/netparams uses this file to compute the |

|---|
| 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. |
