Now use the command “ subnetcalc” in the terminal to calculate the subnet mask for any IP Address as follows.

root@linuxhelppp:~# subnetcalc 192.168.7.228/24
Address       = 192.168.7.228
                   11000000 . 10101000 . 00000111 . 11100100
Network       = 192.168.7.0 / 24
Netmask       = 255.255.255.0
Broadcast     = 192.168.7.255
Wildcard Mask = 0.0.0.255
Hosts Bits    = 8
Max. Hosts    = 254   (2^8 - 2)
Host Range    = { 192.168.7.1 - 192.168.7.254 }
