Consider the following non-default subnet masks: (a) 255.255.248.0, (b) 255.128.0.0 . To which IP address class do they pertain?Write down the following in CIDR notation: (a) IP: 150.160.170.180, Subnet Mask:255.255.224.0; (b) IP: 75.80.85.90, Subnet Mask: 255.252.0.0 Three stations A, B, C and D are connected to a common Ethernet hub. Their IPaddresses and subnet mask are respectively: 200.100.50.67, 255.255.255.252;200.100.50.7, 255.255.255.248; 200.100.50.138, 255.255.255.240 and 200.100.50.1,255.255.255.254. Determine which among these stations can communicate with eachother. You need to show all detailed workings.

In this exercise, we estimate the CIDR address block requirements for TrendyWidgets Inc. For example, if TrendyWidgets needs about 8,000 IP addresses, you would say that TrendyWidgets needs a /19 CIDR block. This is because a /19 address block uses 19 bits for the network part of the IP address, leaving 32 – 19 = 13 bits available for the host part. This allows unique labeling for 213 = 8,192 hosts. Answer the following questions: 1. If each computer on TrendyWidgets’ network is allocated an IP address, how many IP addresses is TrendyWidgets likely to need? 2. Based on this estimate, what is a CIDR address-block size suitable for TrendyWidgets?
