Hello Mahesh you are correct.

here are the details for your /12 address range:

172.16.0.0/12

host range 172.16.0.1 - 172.31.255.254 (available addresses)

Network address 172.16.0.0

Broadcast address 172.31.255.255

Wildcard mask 0.15.255.255

Hope this helps

Hi Inayath,

But this does not calculate 172.16.0.0/12.

Thanks

Hi Mahesh,

It doesn calculate just key in the correct ip address and respective subnet mask and hit the calculate button on this link:

http://www.subnetonline.com/pages/subnet-calculators/ip-subnet-calculator.php

or the other easiet for you to check is:

http://jodies.de/ipcalc

ip address: 172.16.0.0/12

Address (Host or Network)	Netmask (i.e. 24)	Netmask for sub/supernet (optional)
/		move to:

Address:   172.16.0.0            10101100.0001 0000.00000000.00000000
Netmask:   255.240.0.0 = 12      11111111.1111 0000.00000000.00000000
Wildcard:  0.15.255.255          00000000.0000 1111.11111111.11111111
=>
Network:   172.16.0.0/12         10101100.0001 0000.00000000.00000000 (Class B)
Broadcast: 172.31.255.255        10101100.0001 1111.11111111.11111111
HostMin:   172.16.0.1            10101100.0001 0000.00000000.00000001
HostMax:   172.31.255.254        10101100.0001 1111.11111111.11111110
Hosts/Net: 1048574               (Private Internet)

Key in the ip address and netmask it will show you the subnet range.
