For example: This subnet mask is not usable on your network because the leftmost bit is set to 0. Conversely, the rightmost bits in a valid subnet mask must be set to 0, not 1.

For example, the 32 subnet valid hosts are 33-38. Let’s do a fifth example using the Class C mask of 255.255.255.252. Here are the answers: How many subnet bits are used in this mask?

For example, if there is an IP address: 192.168.0.1, it will have 24 host bits and 8 network bits, therefore, its Subnet Masks would 255.255.255.0. Windows allows you to change the Subnet Mask of ...

Our next subnet would be 128.16.8.32 with the same 31 hosts, including broadcast and network. The subnet following that would have an IP range of 128.16.8.64-95. The next would be 128.16.8.96-127, ...

These last 8 are divided between hosts and subnets (for more on network classes, see subnet mask tables). In Example #1 below, the 255.255.255 are the numeric values of three sets of eight 1 bits.

For example, on the 255.255.192.0 mask, the subnetting will be done in the third octet. To create a valid subnet, you must add the fourth octet of all 0s and all 1s for the network and broadcast ...
