2 y – 2 = number of hosts per subnet. y is the number of 0s in the subnet mask. Subnetting example. An example will help you understand the subnetting concept. Let’s say that we need to subnet a class C address 192.168.0.0/24. We need two subnets with 50 hosts per subnet. Here is our calculation: 1. Since we need only two subnets, we need 2
A subnet mask (or net-mask) is made up of 32-bits, like a regular IP address, but is used only to divide the subnet bits from the host bits. The subnet bits are all 1s and the host bits are all 0s. So a subnet mask might be 11111111.11111111.1111111.00000000, which in decimal should be 255.255.255.0.

Increasing the number of IP addresses on a subnet in DHCP
This subnet calculator can help you with the following tasks: Identify subnet parameters for a given IP address and subnet mask (or CIDR prefix). Display subnet parameters for a number of consecutive subnets of the specified length. Enter IP address value either in dot-decimal notation (e.g., 10.1.1.5) or in CIDR notation (e.g., 10.1.1.5/24). Dec 11, 2009 · Make the W2K server's DHCP service authoritative for the scope 192.168.0.1 - 192.168.1.254 - Yes just create another scope if you need to 2. Change the DHCP subnet leasing to 255.255.0.0 - Yes this extends the "collision domain" to both subnets
