IP Addressing and Subnetting

By Charles C. Botsford
This " Free, Lecture-Based Presentation on IP Addressing and Subnetting" was created to teach computer professionals how to address IP networks and perform subnetting. Subnetting is one of the most difficult activities network technicians are required to perform. Many people have found viewing these presentations multiple times increases understanding. Use these methods for success:
  • View and listen to the sections in consecutive order. Each section relies on information from the previous sections. (The entire course takes about two and half hours.)
  • Print Out Practice Problems and Section Helpers before you view the presentation (where available).
  • Take notes, and refer to the Section Helpers while you listen to and view the presentation.
    Perform the Practice Problems to sharpen your skills.
  • Be prepared to re-view key modules where needed (usually three times is standard).
  • View summary sections to reinforce key concepts.

For test takers:

  • Learn Subnet ID/Host Charts that are a part of the "Subnetting Section Helper"
  • Practice twice a day for a week
  • Before you click start on the test, write down Subnet ID/Host Charts from memory on paper provided at testing center. (Do NOT smuggle in charts or violate testing rules!)
  • Use Charts to lookup answers to subnetting questions!
