Hi, I’m Ed Liberman. My series of free videos on TCP/IP and Networking Fundamentals covers all of the basics you need to truly understand TCP/IP and get a solid foundation in networking.
This free video series focuses on TCP/IP theory and some important networking concepts including the OSI model, IP addressing, binary numbers, IPv6 and more.
Check out the videos and let me know what you think!
Just a quick course intro, only about half a minute long.
Lesson 2: What is a Protocol
Learn what a protocol is and how it is used for communication between computers on a network. You will also get a chance understand the OSI model — what it is and what it does.
Runtime: 19 min
Lesson 3: What is TCP/IP?
Gain an understanding of what TCP/IP is by learning about the architecture and the different protocols, including the Transport Layer and Internet Layer protocols, that work together to make up the TCP/IP protocol suite.
Runtime: 16 min
Lesson 4: Configuring an IP Address
Learn what an IP Address and Subnet Mask are and how they work together. Practice configuring an IP address, viewing a computer’s IP configuration, and checking for connectivity with other computers.
Runtime: 15 min
Lesson 5: IP Address Planning
This video discusses planning an IP addressing scheme, rules for IP addressing, classful IP addressing, and Network Address Translation (NAT). You will also see the difference between private vs. public IP addressing.
Runtime: 18 min
Lesson 6: Binary Numbers
Lesson 6 delves into binary numbers and how they relate to IP addressing. Learn what the difference between decimal and binary numbering systems is, how to convert decimal to binary and how to do it on your calculator.
Runtime: 15 min
Lesson 7: Internetworking
Starting with a brief review of what an IP address is and how it is broken apart, you’ll get a better idea of what a router and default gateway are. The video focuses on internetworking providing you with an introduction to client configuration and subnetting.
Runtime: 16 min
Lesson 8: Classless Interdomain Routing (CIDR)
Lessono 8 focuses on Classless Interdomain Routing (CIDR) and covers:
• Problems with Classful IP Addressing
• Variable Length Subnet Masks
• Subnetting with CIDR & VLSM
• Formulas
• Basic Network
• CIDR Notation
Runtime: 13 min
Lesson 9: Fundamentals of IPv6
In the last video you will learn the fundamentals of IPv6, including IPv6 solutions and addressing. You will also learn a little bit about IPv4 and its disadvantages.
Runtime: 12 min

I have read a few books to try and learn and understand TCP/IP but never came across anything like your training before. This is the best I have ever seen and now have a better understanding of Networking. I thank you for all your time and effort you have put in to this. Would recommend highly.
Thanks for the time you have taken to put this video together for the benefit of us. I have really learned alot. And it is a quicker way of learning. The videos are really useful. What a good idea. Thanks alot.
WOW! Ed you are by far the finest instructor I have had the pleasure of listening to. I have taken many certification courses from those who have been in the business many years. It takes someone like you ED that can communicate the concepts. making them fun to learn and easy to grasp. Thanks for being a part of TrainSignal. Your style and knowledge will move TrainSignal leaps ahead of the competitors.
Wow!..

Can We use your video to use in our Thesis study?
Your Reply is so much appreciated ..
the videos are not buffering good. can you put in other player? The ooyala player is so bad, i cant play the even after fully buffered, even 246 kbps not working with it with these player, plz change the player or provide me the download link.
This was a great supplement to my networking class … very easy to understand! One problem … I did have issues trying to get the videos to play. Lots of delays …
Hi Liberman,
First of all thanks a lot…
This is Milton from Tamilnadu, India…..
I have gone through your video sessions on TCP/IP……..
Its really stunning………..
what a online material have you given sir…….
this is really a great piece of things for any one who wanna start his career in networks….
Keep up the good work ED………..
Hi.. As you know it seems we are all newbies in this field..
But letx share our knowledge too… Remote Desktop also forms part of Networking..
So here is my “homework”: How can I access a PC (host) from work through an ISP????
I guess you are aware the difference betwn Dynamic and static ip address.. So how can i trace my dynamic IP address from my work if I want to connect my PC..
Wow – I’ve been in the industry for many years and took classes at TSST college awhile back to try to try to get certified and just didn’t grasp some of the Networking concepts. I think I finally got it thanks to your way of communicating and graphics. I now have more confidence in my ability to be very successful for the rest of my IT career
Thanks a million
Keep up the good work
and thanks for offering this for free. I really couldn’t afford the training classes at this time in my life, but desperately need it so I can get some certifications along with my experience, so I really appreciate it
Excellent! I agree with others, it’s been very helpful. I’ve been in the industry for long time and you are the best that has explained these fundamental concepts.Thank you!!
Wow! I am so grateful…. I agree with everyone who has said something positive here. I love this training!
This was a scary subject i.e, networks and internet protocol etc. Now, I feel that I have joined the human race. I only wish that I had known about this as soon as it was available.
