*UPDATED VERSION OF THIS VIDEO: **ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-YJGGYKAV4pA.html* That is the new final video of a 13 part video series discussing Networking Fundamentals. You can see the full series here: ru-vid.com/group/PLIFyRwBY_4bRLmKfP1KnZA6rZbRHtxmXi 👇 Hello, This video is the first video I ever published to RU-vid. Initially, I didn't even mean to create a consistent RU-vid presence, this was simply a topic that I felt was better taught visually. All that said, I've come a long way with video and audio recording quality. I know there are a bunch of issues with the audio in this video, but please understand I was very new at recording videos when I published this in 2016. All my newer content is much, much better quality =) Hope you got a lot out of this, and if you did, I would highly recommend the series I linked above, as it's a much more thorough and expanded version of how Networking works. Cheers! -Ed Practical Networking .net
Network engineer here. This is phenomenal, man. No matter how far I get into this, I always come back to solidify the basics. This is very simply explained, but straight to the point. The fact you included the switch learning the MAC of the ARP sender is a thing I have not seen in many videos. I hope to start making videos like this soon!
Hi Blake! Thanks for the kind words, glad you enjoyed this series. By the way, I updated this video and made it much better: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-YJGGYKAV4pA.html In fact, you might also be interested in the full Networking Fundamentals series: ru-vid.com/group/PLIFyRwBY_4bRLmKfP1KnZA6rZbRHtxmXi
amazing explanation, because u showed every single address at every single point in the journey, which made it really easy to understand, and the animation made it even more understandable , thank you very much sir
Only one sentence, I have for you and that is "You are the best teacher in networking". You explained everything in such a way that any dummy can understand networking basic principles. Thank you very much.
Glad you enjoyed this =) PS: There is an updated version of this video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-YJGGYKAV4pA.html It's from a full Networking Fundamentals series: ru-vid.com/group/PLIFyRwBY_4bRLmKfP1KnZA6rZbRHtxmXi
Hi Nagaram, I'm happy it helped. Posts like this are great encouragements to keep making more videos. Although lately I have been more focused on articles. Just finished a couple on VLANs and their configuration. Check them out here: pracnet.net/vlans
Very straightforward and helpful overview. Would love to see this same style of presentation to explain SDN flow table routing, and also difference between traditional network routing and SDN routing.
This was great! As a suggestion, it would be great to see this tutorial extended to cover routing protocols, eventually explaining a global packet journey from an AS to an another AS.
I've watched the entire series - great stuff, not just for review, but for a bit more insight. Walking through all the protocols makes everything clear.
Always mind-blowing that this process that takes 15 min to describe clearly (not including the various 20 second backups to repeat/hear again), yet this process happens nearly instantly, practically like magic lol. As always, great video and illustration(s). Thank you.
Thank you so much! Finally I faund someone understanding how explain something in logical way. I watched video 5 times. All bloggers must learn from you the right way of explaining.

This is by far the best video I've seen on the subject. The narrative is clearly articulated, the diagrams are well-drawn without sloppy and distracting errors, and the detail is sufficient, without verbosity.
After having it read through books multiple time and never getting it, your short videos and series have given me a better insight. Just wanted to say two things: Awwwwsooomeee and Thankuuuu

I found this video in r/ccna, I have to say I love this so far. Working my way up from your website currently, thanks for the quality information and presentation.
I was trying to learn the concepts and then apply this practical concept myself but I got stuck in the layer 3 to layer 2 translation. Literally nobody tells that Routers maintain an ARP table too! Everyone tells that Routers maintain Routing tables, but nothing else. This video was so good that one can learn the whole Layer 1 to 3 translation within 20 mins! Thanks a lot my guy! ♥️💯🔥
What can I say, This video is absolutely straight forward, it explains the complete details in such a way that can be easily understand. Thanks you so much! i need to review this all over again until it is 100% absorbed.
Glad you enjoyed it, Abel. Just so you know, there is an updated version of this video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-YJGGYKAV4pA.html It's from a full Networking Fundamentals series: ru-vid.com/group/PLIFyRwBY_4bRLmKfP1KnZA6rZbRHtxmXi
@@PracticalNetworking Ed, fortunately for me I a newbie to Netowork engineering looking to take the CCNA exam. I will definitely check your series. Plus any advice from you, regarding taking the CCNA exam as a newbie will be much much much appreciated Ed
Hi Moe, glad it helped you understand! And thanks for being my second comment on RU-vid ;)! Don't forget to read the rest of the articles in the series at pracnet.net/packet-traveling
This is actually perfect. I am a junior network engineer and I wanted to refresh the basics for a job interview this week. Thank you so much for your effort.
Thank you, Fisseha! PS: You might be interested in the updated, full series which elaborates on all the concepts of this video: ru-vid.com/group/PLIFyRwBY_4bRLmKfP1KnZA6rZbRHtxmXi
Wait for what I plan to do with the Networking Fundamentals series. It's going to be like this, but better =) www.practicalnetworking.net/index/networking-fundamentals-how-data-moves-through-the-internet/
Amazing video on packet travelling. Actually, i was going through article present on this but it was difficult to understand from there. Then i got this video which is really nice and easy to understand.
Glad you enjoyed the series, Sourav! PS: There is an updated version of this video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-YJGGYKAV4pA.html It's from a full Networking Fundamentals video series: ru-vid.com/group/PLIFyRwBY_4bRLmKfP1KnZA6rZbRHtxmXi

Have any material explaining the function of static arp entries in the ARP TABLE of the broadcast addresses below? IP address 192.168.1.255 Physical address ff-ff-ff-ff-ff-ff IP address 255.255.255.255 Physical address ff-ff-ff-ff-ff-ff What types of services are they used for? For example: are they used in DHCP? and on Wake On Lan?
Those are the two types of Broadcast IP addresses, I just created content discussing them: Quick Video ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ZNXDbzaAM-I.html Detailed Video ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ny6MsSLb8_o.html Detailed Article www.practicalnetworking.net/stand-alone/local-broadcast-vs-directed-broadcast/
Thank you Jan. Glad you liked it. If you liked this, you'll definitely like my new Networking Fundamentals series: www.practicalnetworking.net/index/networking-fundamentals-how-data-moves-through-the-internet/ I'm planning to "one up" this video in the new series =).
Hi Ram. Because Host A's Default Gateway was configured as 11.11.11.1. That is the IP address the host will use to reach something on a foreign network. More details in this video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-QPi5Nvxaosw.html
A big thumbs up from me ... Although I have one question. In step 2 How does the PC A know or PC will figure out that we need to send ARP frame to 11.11.11.1 instead of 22.22.22.40 ?
Good Question, Rohit, it has to do with Subnetting. When Host A was configured, it was given an IP address (11.11.11.10) and a Subnet Mask (255.255.255.0). Through the magic of subnetting, that will tell Host A that they are on a network which contain the IP addresses 11.11.11.0 - 11.11.11.255. Host A was also configured with a Default Gateway (11.11.11.1). This is the address Host A will use anytime in needs to send a packet to an IP address on a foreign network (i.e., anything other than 11.11.11.0 through .255). Host D's address (22.22.22.40) falls outside this range, so Host A knows the packet must be sent to the default gateway (11.11.11.1). This process is explained further in the article series. Check them out: www.practicalnetworking.net/series/packet-traveling/packet-traveling/
Ok Got it ... Thanks .. There is little request. Can you please take any presentation on switchport ? like Trunk port,Access port and Native ports. By theoretically it looks simple but when we try to understand the ingress/egress packets from these types of ports it is really confusing :). It will be so helpful if you explain with same manner.
Hi Rohit. I've written some articles which covers those subjects exactly. Check them out: www.practicalnetworking.net/stand-alone/vlans/ www.practicalnetworking.net/stand-alone/configuring-vlans/ www.practicalnetworking.net/stand-alone/routing-between-vlans/
Somehow I missed this comment. But you are correct, what I wrote can be misinterpreted to imply the default gateway is "figured out" automatically. I've updated the post to clarify. Thank you for pointing this out.
i usually do not comment, but this video is the best video for packet traveling that i have found so far. thanks a lot for this video, also for the article it is one of the best article in your website.

Want to learn more about Networking? ... or, are you Studying for your CCNA? If so, here is a list of all my free CCNA related content: www.practicalnetworking.net/index/ccna/
hopefully ur not tired of hearing this but this is the best video or explanation so far...i can't count how many other videos i've watched but it was a lot. thanks!
Hey RU-vid, if you found this video helpful, please share it across your social networks! Also, you may enjoy this short video that explains ARP in less than 5 minutes: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-QPi5Nvxaosw.html
Awesome!!! Host(ARP Table), Switch(MAC Address Table - for each switch port), Router(ARP Table & Routing Table) - Are all well explained in "Packet Journey".
Hey RU-vid! Want to master subnetting? These are the only videos you'll ever have to watch: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-BWZ-MHIhqjM.html
I just want to say thank you. That was incredibly good and thorough explanation. I really wish to understand better docker containers networking. Do you have any resources where I can learn? One more thing, do you have any ideas and could provide at the end of videos some practical assignments? Although I've understood everything, sometimes when it comes to reality it turns out that I understood something mistakenly.
@@dawidnazarko926 Sorry, somehow I've only just seen this comment! I'm afraid I don't have any suggestions on resources for Docker networking. As for practical assignments, I usually suggest students rebuild the lab topologies they see in videos in GNS3 or Packet Tracer and validate everything they've learned against real gear. That way they aren't just taking the instructor's word for it, but are actually proving it to themselves.
keep doing what you are doing, you are serving humanity at best. You have an ingenious way of sharing your knowledge with those who need it. Your students are following your lead so please keep making more of these videos.
Thanks very much for creating this series. This makes the things very easy to learn. highly recommends for the folks who wants to learn the packet routing from host A to host B
Thank you so much...i have been trying to grasp this idea of what happens if the host is on another network and how will the data move through routers and switches in between and thank God i stumbled upon your websites and read your articles and now videos...Helped me a lot in understanding the ARP and How netwroks work. Thank you
Remarkable work that you have put them together ! I input so many hours to read/understand these concept and there is some fraction is still unclear. With a video of 14:38 minutes that explains everything that I need to know. Thank you so much ! If you can't explain it simple, you don't understand it well enough. Albert Einstein
So glad this helped you, Sousou =). Interestingly enough, that is the exact quote I have at the bottom of my about page on my website: www.practicalnetworking.net/about/
@@PracticalNetworking I saw you have cryptography and I was wondering will you make videos on the Network Security side ? Many thanks again for the link and very helpful on my study !
Amazing Video and presentation. I have watched all the 7 videos of the Subnetting series. I was confused as I am preparing for my new CCNA certification by not able to understand the subnetting concepts, like binary method, pie chart method, few second subnetting and magic number methods. After a lot of search I found your video. The table is enough for subnetting and you have explained every step for all the three Octets and nailed down how to speed up the complicate steps as well. Great Man.. Excellent . Keep it up ..The way of your presentation is very clear and simple...
Thanks for the kind words, Karthikeyan, I'm so glad you got a lot out of the Subnetting series and the Packet Traveling video! I hope to keep making more videos as time goes on!
Beautiful explanation, thank you. This definitively gave me a stronger understanding, I'm currently studying to take the ccna exam and I find this so very helpful.
