Dengan menggunakan IPCalc (Kalkulator IP) kita bisa dengan mudah mengetahui subnetmask, ip network, ip broadcast, dan jumlah ip host.

Install ipcalc di Ubuntu
$ sudo apt-get install ipcalc
Cara Pemakaian
$ ipcalc 192.168.0.1/24
Address:   192.168.0.1          11000000.10101000.00000000. 00000001
Netmask:   255.255.255.0 = 24   11111111.11111111.11111111. 00000000
Wildcard:  0.0.0.255            00000000.00000000.00000000. 11111111
=>
Network:   192.168.0.0/24       11000000.10101000.00000000. 00000000
HostMin:   192.168.0.1          11000000.10101000.00000000. 00000001
HostMax:   192.168.0.254        11000000.10101000.00000000. 11111110
Broadcast: 192.168.0.255        11000000.10101000.00000000. 11111111
Hosts/Net: 254                   Class C, Private Internet
$ ipcalc 192.168.0.1/255.255.255.240
