How to find the Subnet Address in Computer Networks

How to find the Subnet Address ?

 

AND (logical AND Operation) the subnet mask with any valid host IP address on the network will yield the subnet address.

Example

Given the subnet mask and any valid host IP address,

Subnet mask is        255.255.255.240
Host IP address       200.129.  41.23

Find the corresponding subnet address?

Subnet mask is        255.255.255.240 = 255.255.255.1111 0000

Host IP address       200.129.  41.23    = 200.129.  41.0001 0111


Last octet to binary:        200.129.  41.0001 0111
AND
subnet mask:          255.255.255.1111 0000

                                  200.129.  41.0001 0000

Subnet Address:                 200.129.  41.16
