5.3 5.4 You have been assigned the task to set up a LAN subnet. Unfortunately, due to certain logistical problems, one of the devices that has to be connected to this subnet has a static IP address that cannot be changed. This IP address is 193.13.11.11. The network has to have enough addresses for 863 devices. This network is new enough that all of the devices can have classless addresses. Considering this information, determine the: Subnet mask; Network address; Broadcast address; Smallest device address; and Largest device address. (5) It has been some time since the subnet has been set up, and one of the network devices has failed. The only substitute device is too old for classless addressing. All of the devices in the subnet therefore now have to use classful addresses. Determine a classful subnet mask and classful IP addresses for the network that contains the address 193.13.11.11. The network now needs addresses for only 745 devices. (5)
