## Analyzing IP Networks Exercise 1

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:
1. Find the Network ID
2. Find the Network Broadcast Address
3. 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.
