suppose we have an address 10.23.2.1 and another address 255.255.255.0, now there binary representations are:

10.23.2.0: 00001010 00010111 00000010 00000000

255.255.255.0: 11111111 11111111 11111111 00000000

Now we'll mark the bits that are in 1's in the first address

which are: 00001010 00010111 00000010

i.e. 10.23.2, hence all the IP addresses belong in the reange 10.23.2.0/255.255.255.0 fall under the same subnet.

In binary form, let's visualize how the subnet mask marks the bit locations common to a subnet. Consider an IP address, say 10.23.2.2, and its corresponding subnet mask, 255.255.255.0. Now, let's represent them in binary:

IP Address 10.23.2.2: 00001010 00010111 00000010 00000010

Subnet Mask 255.255.255.0: 11111111 11111111 11111111 00000000

Next, we mark the bits that are set to 1 in the subnet mask on the IP address:

Marked bits: 00001010 00010111 00000010

This marked portion, i.e., 10.23.2, signifies the common part of the subnet. Therefore, any IP address falling within the range 10.23.2.0/255.255.255.0 is part of the same subnet. This illustrates how subnet masks help define and group IP addresses within a network.
