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

Subnet Calculation for Class C IP address

root@linuxhelp:~# subnetcalc 192.168.5.20/24 
Address       = 192.168.5.20
                   11000000 . 10101000 . 00000101 . 00010100

Netmask       = 255.255.255.0
Broadcast     = 192.168.5.255
Wildcard Mask = 0.0.0.255
Hosts Bits    = 8
Max. Hosts    = 254   (2^8 - 2)
Host Range    = { 192.168.5.1 - 192.168.5.254 }
Properties    =
   - 192.168.5.20 is a HOST address in 192.168.5.0/24
   - Class C
   - Private
GeoIP Country = Unknown (??)
DNS Hostname  = (Name or service not known)

Subnet Calculation for Class B IP address

root@linuxhelp:~# subnetcalc 172.25.0.11/16  
Address       = 172.25.0.11
                   10101100 . 00011001 . 00000000 . 00001011

Wildcard Mask = 0.0.255.255
Hosts Bits    = 16
Max. Hosts    = 65534   (2^16 - 2)
Host Range    = { 172.25.0.1 - 172.25.255.254 }
Properties    =
   - 172.25.0.11 is a HOST address in 172.25.0.0/16
   - Class B
   - Private
GeoIP Country = Unknown (??)
DNS Hostname  = (Name or service not known)

Wildcard Mask = 0.255.255.255
Hosts Bits    = 24
Max. Hosts    = 16777214   (2^24 - 2)
Host Range    = { 10.0.0.1 - 10.255.255.254 }
Properties    =
   - 10.20.14.12 is a HOST address in 10.0.0.0/8
