Subnet Mask Cheat Sheet If you are a network admin like us, this is a little sheet that you will continually need access to. We hope you find it as helpful as we do.
For IPv4, networks can also be characterized using a subnet mask, which are sometimes expressed in dot-decimal notation, as shown in the "Subnet" field in the calculator. All hosts on a subnetwork have the same network prefix, unlike the host identifier which is a unique local identification. Jul 13, 2017 · A subnet mask is a 32-bit number used to differentiate the network component of an IP address by dividing the IP address into a network address and host address. It does so with bit arithmetic whereby a network address is bit multiplied by the subnet mask reveal the underlying subnetwork. Aug 26, 2011 · CIDR. Subnet Mask. Total IPs. Usable IPs /32: 255.255.255.255: 1: 1 /31: 255.255.255.254: 2: 0 /30: 255.255.255.252: 4: 2 /29: 255.255.255.248: 8: 6 /28: 255.255.255 Instead, the subnet mask is used to determine whether a destination IP address is on the local subnet or whether it is in some remote subnet and has to be sent to the router for onward destination. That determination occurs on the host. The explanation of how the subnet mask works is sub-optimal. The host determines where to send an IP datagram IPv4 subnet mask is 32 bits large. In a valid subnet mask network part is represented with "1" from left side followed and ended by host part "0" - 11111111.11111111.11111111.00000000 (binary form), 255.255.255.0 (dotted-decimal form) or simply "/24" (where 24 represents that subnet network part is 24 bits long). A subnet mask is used to identify the part of the address that should be used as the Subnet ID. The subnet mask is applied to the full network address using a binary AND operation. AND operations operate, assuming an output is "true" only when both inputs are "true." Otherwise, the output is "false."

The subnet mask is the network address plus the bits reserved for identifying the subnetwork -- by convention, the bits for the network address are all set to 1, though it would also work if the bits were set exactly as in the network address. In this case, therefore, the subnet mask would be 11111111.11111111.11110000.00000000.
