Once you have decided to divide a network into subnets, you’ll need a subnet mask. But I was wondering if anyone can provide me justification on how to determine the specific IP or range of IP addresses are covered by their subnet mask or by calculating wild card mask. Subnetting is the process of designating some high-order bits from the host part as part of the network prefix and adjusting the subnet mask … Subnet Mask for IP Address is calculated by setting all the bits reserved for network ID and subnet ID to 1 and all the bits reserved for Host ID to 0. The result of the bitwise AND operation of IP address and the subnet mask is the network prefix 192.0.2.0.The host part, which is 130, is derived by the bitwise AND operation of the address and the one's complement of the subnet mask.. Subnetting. Archive Have a look in the archives for the new version 0.41, with the capability to deaggregate network ranges How to run this under windows Answer is 1. To calculate the IP Address Subnet you need to perform a bit-wise AND operation (1+1=1, 1+0 or 0+1 =0, 0+0=0) on the host IP address and subnet mask.
