a) You are designing a subnet mask for the 172.10.0.0 network. Apply the sub-netting technique to break the given network into 170 subnets with up to 240 hosts on each subnet. b) Apply the sub-netting technique to conclude how many subnets and hosts per subnet you can get from the network 172.16.0.0/20? c) Apply the sub-netting technique to conclude what is the broadcast address of the network 220.207.176.0 255.255.240.0? Explain with proper reasoning. d) What is the last valid host on the sub network 192.168.10.240 255.255.255.240? e) Explain that how IPv6 Link Local address is generated through EUI-64 process, given the physical address of the device is FC: 99: 47: 75: CE: E0.
