Calculate the Network Address, the broadcast address and the host range, for the following host address
i. 192.168.180.94/27
ii. 172.23.8.19 /21
iii. 147.252.238.20 255.255.240.0
b. Consider three LANs interconnected by two routers as shown in Figure below. Assign IP addresses to all of the interfaces. For Subnet 1 use addresses of the form 192.168.1.xxx; for Subnet 2 use addresses of the form 192.168.2.xxx; and for Subnet 3 use addresses of the form 192.168.3.xxx. [use CIDR notation]
