Hey, sipcalc is neat. It almost certainly eclipses the need for this
package. Compare outputs:

mfincham@michael-desktop:~/Working/whatmask$ whatmask 192.0.2.1/24

------------------------------------------------
           TCP/IP NETWORK INFORMATION
------------------------------------------------
IP Entered = ..................: 192.0.2.1
CIDR = ........................: /24
Netmask = .....................: 255.255.255.0
Netmask (hex) = ...............: 0xffffff00
Wildcard Bits = ...............: 0.0.0.255
------------------------------------------------
Network Address = .............: 192.0.2.0
Broadcast Address = ...........: 192.0.2.255
Usable IP Addresses = .........: 254
First Usable IP Address = .....: 192.0.2.1
Last Usable IP Address = ......: 192.0.2.254

vs:

mfincham@michael-desktop:~/Working/whatmask$ sipcalc 192.0.2.1/24
-[ipv4 : 192.0.2.1/24] - 0

No. 

whatmask may have already reached its useful EOL, given these two
