Analyzing IP Networks Exercise 1
By certskills
This is the My Dear Aunt Sally (Multiplcation/Division/Addition/Subtraction) of the IP addressing and subnetting world. Nothing snazzy, just some extra exercises, and place to ask questions. Today’s post lists sample problems, the follow-up post will show the answers.

Five Problem Statements
Each problem starts with a Dotted Decimal Notation (DDN) number. Your job:
- Determine the class (A, B, C, D, E, or none)
- If A, B, or C:
-
- Find the Network ID
- Find the Network Broadcast Address
- Find the numerically lowest and highest IP addresses that can be used by hosts in the network
Table 1 lists the five problems.
Table 1: Five Problems for Today’s Post
| DDN Value | Class | |
| 1 | 100.100.100.100 | |
| 2 | 200.200.200.200 | |
| 3 | 300.300.300.300 | |
| 4 | 128.128.128.128 | |
| 5 | 191.191.191.191 |

Hello Wendell. I noticed that you did not overtly specify that we were to use the “basic-defaults” of subnet masks for each network-class (or did I miss something). But I did so, and got everything correct.
But it was much too easy if you really wanted to test our grasp of the information.
Hi Jeff,
Thanks for the constructive feedback – always appreciated.
