*UPDATED VERSION OF THIS VIDEO: **kzread.info/dash/bejne/i357qbuEcbmaoKQ.html* That is the new final video of a 13 part video series discussing Networking Fundamentals. You can see the full series here: kzread.info/head/PLIFyRwBY_4bRLmKfP1KnZA6rZbRHtxmXi 👇 Hello, This video is the first video I ever published to KZread. Initially, I didn't even mean to create a consistent KZread 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

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.

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.

If you are in a break/fix situation, this is perfect!

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: kzread.info/dash/bejne/g4Sdl7CvqMTVo9o.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 ?

@PracticalNetworking

7 жыл бұрын

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.
