The three subnet addresses can be summarized into one supernet address of 192.168.0.0/16, which covers all the addresses from 192.168.0.0 to 192.168.255.255. This is because the first two octets of these subnets are identical (192.168) and the third octet of each subnet is consecutive (64, 128, 192). By combining them into a /16 network, the common bits are preserved while the different bits are ignored in the summary.
