Course 2213 IP Networks, Routers and Addresses

IP Addresses • Packets • Networks • Routers • Static and Dynamic Addresses • DHCP • Public and Private Addresses • NAT • IPv6

IP Networks, Routers and Addresses is a comprehensive course on IP networking fundamentals: IP packets, IP addressing and IP routers.

We’ll see how routers implement the network with packet-switching, that is, relaying packets from one circuit to another, and how routers are a point of control for network security. We’ll introduce the term Customer Edge (CE), and understand the basic structure and content of a routing table.

Then we’ll cover the many aspects of IP addressing: IPv4 address classes, dotted decimal, static vs. dynamic addresses, DHCP, public vs. private addresses, Network Address Translation, and finish with an overview of IPv6.

“Awesome course, really. Just very, very good.”
  – Tim Wilson, Ciena

“Thank you guys so much, this class was amazing! I would take this all over again!”
– Austin Thompson, NHC

“Since I am very new to telecom, this helped me connect the dots, the different layers and terminology. I liked that it followed the printed workbooks very closely so I could read the summaries after the lessons. The instructor was great. He kept it light, added some jokes to keep it entertaining. I liked most when he did drawings with his explanations.”
  – Ashley Brinkman, Marketing Manager, MTA, Palmer Alaska

“The course was very beneficial for me. I wish I would have been able to take this class a few years back when I first started!”
  – Tamara Pepin, CRTC

“I had some of the basics; this class filled gaps and added much more depth. Instructor Richard was open to questions at any time, and revisited topics until we got it. Having the notes in the printed course book to follow along and add to was very helpful. Richard was very passionate about the course material and had great real-life examples.”
– Robert Smieszny, NHC

“Richard is an excellent instructor. He has unmatched knowledge on the subject! He does a fantastic job interacting as if we are physically in a classroom with him!”
– Daniel Herfel, National Institute of Standards and Technology
