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.

    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.
