Question

Quizplus · Accepted Answer

The subnet mask 255.255.252.0 is a supernet mask that covers 4 Class C networks: 192.168.0.0/22. This means that the first 22 bits in the IP address are the network address, and the remaining 10 bits are used for the host address. Therefore, with this supernet mask, the four networks (192.168.0.0/24,192.168.1.0/24,192.168.2.0/24,192.168.3.0/24) can be combined under one routing entry.
