If your lab does not have enough IP, if you expect to use the network number of the largest private address Class B to establish a Class C network 140.116.18.0 to establish the number of these 3 LANs in the laboratory. The host requirements are 120, 60, and 60 respectively. (It must be greater than or equal to the required number when allocating IP) Please provide your plan for each department in the future. a) Network number, b) Netmask (expressed in CIDR), and c) The range of IPs that each department can actually assign.
