A subnetwork or subnetting refers to the partition of an IP network which is divided into two or more networks. They are designed by accepting bits from the IP address's host part and solving the shortage of IP addresses over the Internet. Take this quiz to test your knowledge about the basics of subnetting. So, let's try out the quiz. All the best!
