Subnetting is the process of dividing one network into smaller networks. Collectively, the smaller networks are referred to as subnetworks (or subnets), and the singular subdivision is a subnetwork (more commonly referred to as a subnet). Every single computer that is connected to a subnet shares an identical portion of the IP address. This shared information is known as a routing prefix, and in IPV4 (Internet Protocol Version 4), the routing prefix is called a subnet mask. The subnet mask is a "quad-dotted decimal representation". This IPv4 Subnet Chart can assist you in looking up how a network is broken up into subnets. Class address ranges:

How many valid host addresses are available on an IPv4 subnet 26?Subnet Cheat Sheet – 24 Subnet Mask, 30, 26, 27, 29, and other IP Address CIDR Network References. What is the usable number of host IP addresses on a network that has a 26 mask?Explanation: A /26 mask is the same as 255.255. 255.192. The mask leaves 6 host bits. With 6 host bits, 64 IP addresses are possible.
