Also, explore hundreds of other math, financial, fitness, and health calculators. Subnet Mask Calculator - Calculate Net Mask, Wildcard Mask Subnet Mask Calculator. The network address and host address are the components of IP address. IP address into the network and host address are separated by the Subnet mask. This IP subnet mask calculator helps you in finding the answer to your question of 'How to calculate a subnet mask?'.

## A network is called a supernet when the prefix boundary contains fewer bits than the network's natural (i.e. classful) mask. A network is called a subnet when the prefix boundary contains more bits than the network's natural mask.. Examples 209.60.128.0 is a class C network address with a natural mask of /24. 209.60.128.0 /22 is a supernet which yields:

The subnet calculator allows the use of a single subnet bit - for example, a class C address with a subnet mask of 255.255.255.128 is permitted. The subnet calculator allows a subnet ID to have its final octet equal to the final octet of its subnet mask - for example, a class C network address of 192.168.0.192 with a subnet mask of 255.255.255

Aug 16, 2003 · [Understanding a subnet mask] Now that you understand what binary is, let's have a look at our two subnet masks from the beginning of my post: 192.168.1.0 / 255.255.255.0 192.168.1.0/24 The concept of a subnet mask is simple. You have a network and you have hosts on the network (anything with an IP address is a host). 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 01, 2020 · It is called a subnet mask because it is used to identify network address of an IP address by perfoming a bitwise AND operation on the netmask. A Subnet mask is a 32-bit number that masks an IP address, and divides the IP address into network address and host address. Subnet Mask is made by setting network bits to all "1"s and setting host bits Subnet Mask Calculator. The network address and host address are the components of IP address. IP address into the network and host address are separated by the Subnet mask. This IP subnet mask calculator helps you in finding the answer to your question of 'How to calculate a subnet mask?'. Class: Size: Subnet Mask: Range of IPs: Class A: 10.0.0.0/8: 255.0.0.0: 10.0.0.0 - 10.255.255.255: Class B: 172.16.0.0/12: 255.240.0.0: 172.16.0.0 - 172.31.255.255
