Subnet Mask Diagram. The 1s represents the network parts and 0s represents the host parts. The subnet mask is 24 bits and the value is 1921681 or we can say 1921681124.
The first subnet mask is therefore 3 octets filled with 1s. The 1s represents the network parts and 0s represents the host parts. If youve poked around the network settings on your router or computer youve likely seen this number.
In ipv4 these subnet masks are used to differentiate the network number and host identifier.
In our example the subnet mask is 1921681124. All 0s in the subnet mask indicate that the corresponding bit of the ip. B for each subnet in your network design. Two way to subnet the masking process are.
