If the IP address was printed on paper we could hide the last byte by placing a paper mask over the number with three holes. Basically, the subnet mask tells the router which numbers it should look at and which ones it should ignore beneath the mask. For example, when a binary mask is laid over an IP address also translated into binary, a 1 over a number tells the router to look at the number beneath, and a 0 says to ignore the number. IPv6 Subnet Cheat Sheet. IPv6 is a complete and different animal as far as subnetting goes. Please note the yellow rows as each has special common use or notes. If there is nothing in the "Amount of a /64" column that means it is to miniscule or to massive to justify calculation. Not much is the same with IPv6 compared to IPv4. 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. The IP Subnet Mask Calculator enables subnet network calculations using network class, IP address, subnet mask, subnet bits, mask bits, maximum required IP subnets and maximum required hosts per subnet. Results of the subnet calculation provide the hexadecimal IP address, the wildcard mask, for use with ACL (Access Control Lists), subnet ID, broadcast address, the subnet address range for the resulting subnet network and a subnet bitmap. The job of a subnet mask is to hide the network element of an IP address. Only the host element is visible. We will explain what a Class C IP address is in more detail later, but one of the most common Class C subnet masks is 255.255.255.0. Like an IP address, each section of the subnet mask address can contain any numbers from 0 to 255. הדבר נעשה באמצעות הגדרה של Subnet mask שמורכבת מ־4 בתים (אוקטאטות). ה־Subnet mask הוא בעצם מספר בינארי בעל 32 סיביות המורכב מרצף של "1" שלאחריו יופיע רצף של "0", לא ניתן לכתוב Subnet mask כך שיופיע "1" לאחר "0".

A subnet mask is used to determine where the network ends and the hosts begin. We get this information by converting the decimal numbers within the subnet mask to binary. The 1's in our binary subnet mask represents the network portion of our IP address, and the 0's represent the hosts.

The subnet mask is a fundamental component of IP subnetting, even though many Network Engineers struggle in fully understanding the meaning. If you are not familiar on how to calculate the subnetting presented in the table above, you might want to have a look at our Easy Subnetting Technique that allows to solve any subnetting problem in less A subnet mask divides the IP address into the network address— ‘masking’ or hiding it — and host address. The host part then can be divided into a subnetwork (or a subnet), and host address, in case there is a need for additional subnetwork to boost performance and security of the network.
