Question

1. Your company has been allocated the Class C network address 200.69.1.0 (i.e. /24). You wish to subnet your network such that each subnetwork in your installation should allow 22 hosts per subnet. Make sure to use / notation when specifying subnet/host addresses. Show reasons/work. Ditto marks may be used where appropriate.

a) List all subnets of our base address using dotted decimal and binary format. Number these starting with #1.

b) List the range of host addresses for subnet #4, using binary and dotted decimal format (list the first 3 and the last 2).

c) List the broadcast address for subnet #5.

2. Which of the following hosts are on the same subnetwork? Must show work.

a) 137.15.116.12/22 b) 137.15.126.63/26

c) 137.15.126.65/26 d) 137.15.119.14/22

Explanation / Answer

a)

b)

c)

d)

Broadcast: 137.15.119.255 10001001.00001111.011101 11.11111111 HostMin: 137.15.116.1 10001001.00001111.011101 00.00000001 HostMax: 137.15.119.254 10001001.00001111.011101 11.11111110 Hosts/Net: 1022

Therefore we can say the hosts 137.15.116.12/22 and 137.15.119.14/22 are on the same subnetwork.
