Hello, when are you planning on finishing the network fundamental course for $59.95? I am interested in studying for the CCNA but would like to add your full course for reviewing all the material before jumping into CNNA study material. I found your way of teaching very efficient and amazing!
For whatever reason it is hard to find networking information as concise as this. Most other books and videos leave me with questions. Every time I think of a question related to what you're explaining, you answer it. This is really great. Thank you!
You helped me pass an interview. Most of the things I learned from your course really came in handy to answer some questions about networking. I would be more than happy to support your course! The way you explain things blows all other videos on this topic away. Seriously, you're the best.
Rick! That's awesome to hear =). Congrats on the passing the interview! Best way to support the course at this time is simply to get the word out about this content. If this video series gains enough traction, I'll start dedicating time to creating the video. Also, reach out to me on Discord. I would love to hear more about the interview and/or how this series helped!
This STYLE OF TEACHING, where everything builds on one another is the proper way of teaching. And this is the best way of learning. I am new to networking and thank god I found this videos because my other studying material is all over the place and its a bit confusing and disorganized. This videos connect the dots much better. I am much more confident about my knowledge after seeing your videos.
I'm liking, commenting on every video to appreciate your work. Seriously man, you have no idea how much headache you're saving everyone by the way you're explaining everything. You, sir, is the best. I've scoured the internet for a video that would actually help me internalize these stuff, and you are the only one who made it possible. Thank you, thank you, thank you, THANK YOU!!!!!!!!!!!!!!!!!!!! If I ever make it anywhere in this field, I would compensate you for this. I'm like a Lannister, and Lannisters always pay their debts.
This is the best networking fundamentals lesson and series I have ever seen. Thank you! Please keep doing what you are doing. I will search your courses first before others.
You networking tutorials are perfect in every way, the way to get this abstract concept across to everybody is not easy, I wonder how many hour you have put in just in order to deliver a 10 minutes presentation. We only wish these super powerful lessons will be constantly delivered and more and more people will benefit from your phenomenal teachings.
Superb series. I had zero networking background just a few weeks ago, and now thanks to these simple yet in-depth lessons, I can understand what networking people are talking about and also to begin learning more advanced concepts. Thank you for sharing this content and most importantly making it available for free.
I learnt subnetting easily with your "Mastering Subnetting" series on TH-cam. Now am learning this series on "Data Flow Through The Internet". You are a genius when it comes to getting across a concept and the detailed steps needed to implement that concept. Thank you for sharing these videos.
This video seriously needs to get much more than 10k views! The best video I have come across that explains exactly how packets travel through networks!
Thank you so much for creating this course! I'm a completely self taught Linux enthusiast and your thorough practical lessons have filled in so many holes in my knowledge and understanding. I will be watching many more of your videos as I learn how to configure my home and office networks to my hearts content. Thank you again
I can tell you're genius friend. You know how to teach and present stuff in such a way that's easy for everyone to understand. I have watched the first 13 video playlists. That was awesome and amazing.
Thank you for the kind words, Amidu. Glad you got a lot out of this series =). Could you do me a favor? Do you mind sharing this video on Linked In, Reddit, Twitter, Facebook, or any other social media you use? As an independent creator, that would be an _enormous_ help, and I would appreciate it _greatly_ .

I cannot comment on your every videos but you are the best explanator. I never watched other videos but i got to know everything from your videos clearly. I would like to have more videos on these kind of topics. Thank you keep it up
I'm currently studying for the Network + cert. Having a hard time visualizing what's being thought in the CompTIA study guide. I stopped with chapter 5 and decided to look for other sources that might help me get a different perspective. I stumbled upon your courses. They're exactly what I have been looking for. Watched the first 6 lessons. I now have a much better idea of what I'm reading in the CompTIA Study guide and will be able to return with renewed hope of better understanding the material. I will be looking for more of your study videos and sharing about them with others. Dave
First of all I want to thank you for the lessons. They are really easy to follow. In practice you usually have to deal with configuring the entire network, whether it is Cisco or Forigate. Especially during migration, for example, which takes place gradually, it becomes very exciting. Because you cannot transfer everything at once. As a result, some applications remain behind that must remain in contact with applications that have already been moved. Perhaps a nice scenario to work out.
This is quality tuition. The combination of easy to follow and detailed graphics and clear speaking make the topic of the video very accessible and easily learned. This is a great series on networking. Thank you for taking the time to create them.
Glad you enjoyed it Colin. Thank you for the kind words. Making these videos takes considerable effort, but it's all stuff I wish someone showed me when I was first learning all this.
@@PracticalNetworking Yes it is, and long may it continue. Skilled and knowledgeable people such as yourself who are willing to teach others are a real credit to the platform too.
Thank you for the instruction. This really helps me understand the things happening when transferring data between networks. I am having an exam about these matters, and some insights in the practice exam are not available in my course material, but to my surprise, I found them here. I was totally blown away and grateful to you.
You're welcome, Nguyen. Glad you found this content helpful. Could you do me a favor? Do you mind sharing this video on Linked In, Reddit, Facebook, or any other social media you use? As an independent creator, that would be an _enormous_ help, and I would appreciate it _greatly_ .
You really make this stuff nice and simple, I appreciate that you make it easy for the watcher to follow along as you take us through some very concise steps. Networking really seems to be well defined but a lot of networking courses have rather poor structures, you structured this course incredibly well and for me this type of structure and quality is what I'll continue to look for throughout my career. Many thanks for your time making these videos and your attention to the quality of each of them.
These series of videos was amazing. I feel like I understand Networks much better than I did before and I think that was because you did an excellent job of breaking things down to very easy to understand steps and ideas. I hope you continue to make IT content!!!
Eyyy a great couple of videos the last 2 related to Routing. I was waiting a long time for them. Really appreciate you make and share this kind of material it is really useful. Keep Rocking!!
Glad you like them, Alonso. I appreciate the kind words. Please help me spread the word about this content =). I'm sure you know people that could also benefit from learning about Routers.
Thank you Alex, glad you enjoyed it =) Could you do me a favor? Do you mind sharing this video on Linked In, Reddit, Facebook, or any other social media you use? As an independent creator, that would be an _enormous_ help, and I would appreciate it _greatly_ .

Again Many Thanks enjoying these as there are also helping me prepare for Networking Plus .Trying to fill in the gaps in my knowledge and get a decent qualification to follow.
Ed you are simply amazing!! The way you explain and simplify complex processes is unbelievably beautiful. I will support you by purchasing some of your courses which are directly in line with what I am studying. Many Many thanks and wish you health and happiness!!
You explain things in an amazing way, it would be nice to see videos about how cloud networking works, and concepts like VPCs, subnets, private links and other cloud networking components
Great course on Networking concepts. Easy to understand and follow, I'm book-marking this to refer back to refresh as needed later. Thanks & Great work!!
Sir, you have a crystal clear concept about networking. I am blessed to get education from you, Thank you Sir. But sir i have a question, why do the two interfaces of router have same ip address?
They shouldn't. Typically, every interface of a Router has it's own IP address. Maybe you're thinking of a L3 switch? This allows multiple physical ports to share the same IP address. Details here: www.practicalnetworking.net/stand-alone/routing-between-vlans/#l3switch
This channel is a blessing for learners of networking. BTW, this is the first module that is free. Do you have other modules as a paid program? Where can I find them?
Hoping to create the rest as a paid course. I'm likely releasing information about this next week. In the mean time, more details are here: pracnet.net/nf
Thanks for the good job with your courses. I have a question about HSRP. How do you configure the Active/Standby routers when using more than 2 routers acting as gateways?
This goes a bit byond what this Series was intending to cover... but the HSRP group# can be shared among more than just two routers if need be (although in reality, this is pretty rare). Feel free to pop in the discord to continue this discussion: pracnet.net/discord
God bless you for what you're doing. My question: In this transit of a data packet from Host A to Host C, there is layer 4 header right? To determine the appropriate port for the packet delivery. Did you skip that for simplicity? Cos you talked about it in the OSI model.
Looks like found the full series, ;) Glad you're enjoying these. I skipped that because it isn't relevant to what Routers are doing. So, while _Yes_, a L4 header exists "behind" the L3 header... from the Router's perspective it's completely arbitrary. It could be TCP, or UDP, or anything else -- either way the Router doesn't "look past" the L3 header in order to Route packets. I'm planning to do a TCP video in the future. I have to finish a few other projects first.
Can someone explain the purpose of ARP mapping between the host and the router, if the router is going to get rid of the L2 layer anyway? It seems like a wasteful step.
Basically, this is what I understand: ARP mapping is done to locate the MAC address. Once the MAC address is located, it then hops to that device, and you no longer need the L2 layer because it was only needed to get from hop to hop. L3 stays from end to end, so that doesn't change, but there may be different L2 (MAC addresses) needed to get to the final destination. I hope that helps.
Great content. I was really hoping you would touch on static routes and next-hop address / exit interface. I seem to get it wrong about half the time, despite for the CCNA for about 9 months. I figured if anyone could make an illustration that would really hammer it home, it'd be you. Thanks so much for all your content. Incredibly well illustrated.
Hi Scott. I know *exactly* what you mean. That is an often confused concept, and I indeed ought to make a video about it. I made a video for Cisco a few years back that covered it exactly. They technically own the video, so I'd have to look into whether I am allowed to re-create a similar video for YT.
Glad you enjoyed them. After you finish the NEtworking series: th-cam.com/play/PLIFyRwBY_4bRLmKfP1KnZA6rZbRHtxmXi.html Consider the Routing Protocols video: th-cam.com/video/KjNYEzEBRD8/w-d-xo.html Then the OSPF series, if you want to go further =) th-cam.com/play/PLIFyRwBY_4bSkwy0-im5ERL-_CeBxEdx3.html
Awesome videos. Just one question. What happens to a packet if it reaches Router where the destination mac address doesnt match (a flood packet reached somehow). Will it discard the L2 header directly as you said irrespective of destination mac matcged or not ? Or it checks and drops the packet as rhe destination mac is not matching ?
Yes, correct. That is part of the role of MACs, so you can tell if something you receive is indeed meant for you. A node will accept a frame only if the L2 destination is it's own MAC address, or a Broadcast MAC address (FFFF).
I have a question about the relationship of ARP and Flooding. During the ARP request, the switch learns from the source. And During the ARP response ,the switch also learns from the responder. Does it mean that when sending the actual data THROUGH the switch, the process bypass the Flooding, and proceed to forwarding? Since the switch already learns during the ARP request-respond process.
Thanks a lot for making it very easy to understand these networking concepts. But I still have 1 questions. After L2 and L3 headers are determined, how a packet is actually delivered from one NIC to another NIC ? I mean, how packets travel from one NIC to another or how do they which computer to go to? Are they physically connected via some dedicated sockets/ports something like that?
Process by which the packet reaches the next host in the path after L2 and L3 headers added to the packet. Should next host and current host on the path be physically connected via wire and switches?
Hello Tutor, Do you mind helping me out with a question on this topic? Must data follow the same path of network(s) it used to arrive to a destination server when returning to the host with a response? I am new to networking and not sure how it works.
Hi Sir, Thank you for making these videos. I have a question regarding switches. I know switches are not the focus of this lesson but I'm looking at my home network and I noticed we only use routers. No switches. So how will a router forward a packet to a host directly if there are no switches?
Loved the clarity on this otherwise complex topic. Have a question - at 4:07 mark, Why would Host A not do an ARP directly for Host C (is it because it is in another network and Host A has that information basis C's IP)? Assuming that is true, how would Host A know IP address of Router 1 to do ARP?
Because Host C is on a foreign network, and the path to a foreign network always runs through the default gateway. This is elaborated in Lesson 3 of this series that discusses everything hosts do to communicate. pracnet.net/nf

just amazing explanations for everything. easy to understand. thank you for your effort and hardwork..
This channel is a blessing for learners of networking.
BTW, this is the first module that is free. Do you have other modules as a paid program?
Where can I find them?
Hoping to create the rest as a paid course. I'm likely releasing information about this next week. In the mean time, more details are here: pracnet.net/nf
Thanks for the wonderful series waiting for the full course
Thanks for the good job with your courses. I have a question about HSRP. How do you configure the Active/Standby routers when using more than 2 routers acting as gateways?
This goes a bit byond what this Series was intending to cover... but the HSRP group# can be shared among more than just two routers if need be (although in reality, this is pretty rare). Feel free to pop in the discord to continue this discussion: pracnet.net/discord
I'm in Love with this video series❤💯
Best series thank you sir !
Thanks for the great explanation, can't wait to see part 6 & 7 :)
You're welcome, Hussam =). Looking forward to getting those released as well!
Did you complete the full course? If so, could you point me to where i can purchase it? Your teaching style is superb!!!! Thank you.
Great Tutorial. Explained with great effort and illustrations. Many Thanks to you....
Thanks again, Jaikishan =). You're very welcome!
Got a clear concept in networking fundamentals and loved your presentation skills.
keep doing good work sir.
may god bless you :)
Muchas Gracias!
De nada!
God bless you for what you're doing. My question: In this transit of a data packet from Host A to Host C, there is layer 4 header right? To determine the appropriate port for the packet delivery. Did you skip that for simplicity? Cos you talked about it in the OSI model.
Looks like found the full series, ;) Glad you're enjoying these.
I skipped that because it isn't relevant to what Routers are doing. So, while _Yes_, a L4 header exists "behind" the L3 header... from the Router's perspective it's completely arbitrary. It could be TCP, or UDP, or anything else -- either way the Router doesn't "look past" the L3 header in order to Route packets.
I'm planning to do a TCP video in the future. I have to finish a few other projects first.
Thanks again for these videos. Very clear and presented in a way that we can understand and remember!
You're welcome, Ward =)
concepts explained very well. thank you so much 🍀
You're welcome again =)
Yes I have enjoyed the lesson! Thanks a lot! You’re great!
Glad you enjoyed the lesson! Thank you for the kind words!
Can someone explain the purpose of ARP mapping between the host and the router, if the router is going to get rid of the L2 layer anyway? It seems like a wasteful step.
Basically, this is what I understand: ARP mapping is done to locate the MAC address. Once the MAC address is located, it then hops to that device, and you no longer need the L2 layer because it was only needed to get from hop to hop.
L3 stays from end to end, so that doesn't change, but there may be different L2 (MAC addresses) needed to get to the final destination. I hope that helps.
Truly deserves....hats off
CHeers, Gaurav =)
Great content. I was really hoping you would touch on static routes and next-hop address / exit interface. I seem to get it wrong about half the time, despite for the CCNA for about 9 months. I figured if anyone could make an illustration that would really hammer it home, it'd be you. Thanks so much for all your content. Incredibly well illustrated.
Hi Scott. I know *exactly* what you mean. That is an often confused concept, and I indeed ought to make a video about it.
I made a video for Cisco a few years back that covered it exactly. They technically own the video, so I'd have to look into whether I am allowed to re-create a similar video for YT.
Amazing videos. ...want to more vids on this topics
Glad you enjoyed them. After you finish the NEtworking series:

Wish I could give you 💯 likes on each of ur videos....they r so good. Thanks Sir...
Thank you for the kind words, Nn =).
i like before i watch
Very interesting and very clear. Thank You.
Awesome videos. Just one question. What happens to a packet if it reaches Router where the destination mac address doesnt match (a flood packet reached somehow). Will it discard the L2 header directly as you said irrespective of destination mac matcged or not ? Or it checks and drops the packet as rhe destination mac is not matching ?
Yes, correct. That is part of the role of MACs, so you can tell if something you receive is indeed meant for you. A node will accept a frame only if the L2 destination is it's own MAC address, or a Broadcast MAC address (FFFF).
Great explanation, i got the concept easily thanks a lot.. keep it up im learning from your channel its helps me in the university thanks again
Glad this is helping you, Wael. You'll probably enjoy the full series this video came from: th-cam.com/play/PLIFyRwBY_4bRLmKfP1KnZA6rZbRHtxmXi.html
Thank you for the video!
I have a question about the relationship of ARP and Flooding.
During the ARP request, the switch learns from the source.
And During the ARP response ,the switch also learns from the responder.
Does it mean that when sending the actual data THROUGH the switch, the process bypass the Flooding, and proceed to forwarding?
Since the switch already learns during the ARP request-respond process.
Great work !
You're 01 all time YT'r
دمت گرم واقعا تو عااااالی هستی🎉
Thanks a lot for making it very easy to understand these networking concepts. But I still have 1 questions. After L2 and L3 headers are determined, how a packet is actually delivered from one NIC to another NIC ? I mean, how packets travel from one NIC to another or how do they which computer to go to? Are they physically connected via some dedicated sockets/ports something like that?
Are you asking about the technology which actually transmits the 1s and 0s? Or the process by which the "next hop in the path" is determined?
Process by which the packet reaches the next host in the path after L2 and L3 headers added to the packet.
Should next host and current host on the path be physically connected via wire and switches?
Hello Tutor, Do you mind helping me out with a question on this topic? Must data follow the same path of network(s) it used to arrive to a destination server when returning to the host with a response? I am new to networking and not sure how it works.
Great question. No, data is not required to flow through the same return path as the forward path.
Does routing table really have an entry called left, right? Or is it more like interface ID?
Excellent ... well done ...
Thanks for this informative video..
Awesome!!!! Thanks PN Hoping for your 1M subscriber!!!!!!!
You're very welcome. I hope so too =). Cheers!
You are the best.
Thank you, Azza!
Hi Sir, Thank you for making these videos. I have a question regarding switches. I know switches are not the focus of this lesson but I'm looking at my home network and I noticed we only use routers. No switches. So how will a router forward a packet to a host directly if there are no switches?
Perfect video very good and informative work 👍👍👍
Thanks Jamal. I appreciate the kind words!
Loved the clarity on this otherwise complex topic. Have a question - at 4:07 mark, Why would Host A not do an ARP directly for Host C (is it because it is in another network and Host A has that information basis C's IP)? Assuming that is true, how would Host A know IP address of Router 1 to do ARP?
Because Host C is on a foreign network, and the path to a foreign network always runs through the default gateway. This is elaborated in Lesson 3 of this series that discusses everything hosts do to communicate. pracnet.net/nf
