You will subnet the network address 172.31.103.0/24. the network has the following requirements: · room-114 lan will require 27 host ip addresses · room-279 lan will require 25 host ip addresses · room-312 lan will require 14 host ip addresses · room-407 lan will require 8 host ip addresses how many subnets are needed in the network topology?
