[X-Unix] ipcalc for OS X?

[Jakob Peterhänsel]

Hi,

I'm using the CLI version of WhatMask:

whatmask v1.2, Copyright (C) 2001-2003 Joe Laffey

This binary compiled on 12/10/03 at 16:07:24

to redistribute it under the terms of GNU PUBLIC LICENSE.

whatmask may be used two ways:

Given a mask:          whatmask <CIDR bits>
                - or -  whatmask <subnet mask>
                - or -  whatmask <hex subnet mask>
                - or -  whatmask <wildcard bit mask>
  NOTE: whatmask will autodetect the input and show you all four.

Given an ip/mask:      whatmask <IP address>/<netmask>
        <netmask> may be one of the following:
                        CIDR notation (e.g. "24")
                        Netmask notation (e.g. "255.255.255.0")
                        Hex Netmask notation (e.g. "0xffffff00")
                        Wildcard bits notation (e.g. "0.0.0.255")
  NOTE: whatmask will autodetect the netmask format.

Exsample outputs:

jp% whatmask 24

---------------------------------------------
        TCP/IP SUBNET MASK EQUIVALENTS
---------------------------------------------
CIDR = .....................: /24
Netmask = ..................: 255.255.255.0
Netmask (hex) = ............: 0xffffff00
Wildcard Bits = ............: 0.0.0.255
Usable IP Addresses = ......: 254


jp% whatmask 10.0.0.34/29

------------------------------------------------
            TCP/IP NETWORK INFORMATION
------------------------------------------------
IP Entered = ..................: 10.0.0.34
CIDR = ........................: /29
Netmask = .....................: 255.255.255.248
Netmask (hex) = ...............: 0xfffffff8
Wildcard Bits = ...............: 0.0.0.7
------------------------------------------------
Network Address = .............: 10.0.0.32
Broadcast Address = ...........: 10.0.0.39
Usable IP Addresses = .........: 6
First Usable IP Address = .....: 10.0.0.33
Last Usable IP Address = ......: 10.0.0.38


Hope it helps,
