While subnetting you are utilizing a subnet veil to take bits from the host part of a location and adding them to the organization bit to tailor the number of hosts you can oblige. A subnet cover is a 32-digit number like an IP address, yet as opposed to being utilized for having tended to, its motivation is to impart the parts of an organization address that are network/subnet bits and the bits that have bits. Subnet veils are developed by setting the entirety of the host pieces to 0 and the entirety of the organization/subnet pieces to 1.

Since there are 32 absolute pieces in an IPv4 address (eight in every one of four octets), to track down the number of host addresses obliged by a specific veil you deduct the number of organization bits and subnet bits from 32 and raise 2 to the force of the distinction. For instance, for a/22 organization the quantity of host locations would be 32 – 22 = 10, 210 = 1024 locations. This outline shows the number of host addresses related to various covers:

Whenever you have chosen the number of hosts tends you need, include the paired pieces from both the organization parcel and the subnet partition for every octet independently, and you will have your subnet veil.
