7 A home used wireless router" is usually a multi-function device, apart from Diting. what other functions does it have? List four of them. routing. (c) List five security benefits of subnetting 3. (9 points) (a) Universities typically use Class B type IP address (e.g, 129.207.230.31).If PVAMU needs to organize 60 sub LANs with 500 hosts in each LAN. Design an appropriate subnet addressing scheme. If more than one schemes are available, please list all of them. (b) If the subnet mask is 255.255.240.0 and three computers' IP addresses are 150.100.64.178, 150.100.78.100, and 150.100.80.138, what are the subnet IDs of these computers? Are there any computers in the same subnet? If yes, list the computers. If not all computers are in the same subnet, design a new subnet mask with minimum number of 1's which can partition all three computers into different subnets (show all calculation details)
