    Was looking for something to explain this to a colleague. This fit perfectly. Thankyou. One NitPick: around the 6:00 point, you decapsulate the IP packet from the Ethernet Frame, then put it back into the same Frame. I think it would be clearer if you scrap the old Frame and create a new one with Src-MAC of the router port and the Dest-Mac of the final host. Still one of the clearest videos i could find online. Thanks!

    finally i understood how the mac is used in combination with ip. Thank you very much. And for those wondering how to obtain the MAC/IP combination of local device (eg. the gateway), the answer is the Access Resolution Protocol (ARP). for a practical overwiev in Windows: open commandline (cmd or powershell ) and run first IPCONFIG and afterwards ARP -A

    Deez Skates the latest CCNA does go into visualizing how frames get forwarded in a network quite extensively. I agree with you that nailing it down is absolutely crucial in understanding networks, especially from a troubleshooting perspective. To give an example. One time, random hosts on the LAN were getting a 169 address. My boss told me that it’s probably the switch or the cabling. But I was explaining it to him that it has something to do with the firewall (dhcp server). Because a bad uplink cable would cut off everyone. You can’t have some hosts working and some not on a faulty ethernet cable, because the frames are multiplexed across a single pair of wires. The example is to illustrate that troubleshooting requires understanding the details of the technology. Also another time it happened, he was fiddling with the modem. I explained to him that a bad WAN connection can’t cut off your local IP address assignments.

    Hear me out with this analogy. I see this as me sending out a letter (packet), which in this case my computer IP is my address, and the recipient's IP is where the letter is addressed to. Before I can send it I package the envelope into a FedEx box that has the FedEx tracking number (the Mac address). Once the package is received to the truck driver (the network), he scans the tracking number and takes it to the warehouse (router). The only deviation here is that the warehouse takes that tracking number, and assigns it a new one (other Mac address, which is now picked up and scanned by a second truck driver (2nd network) to get it delivered to the new address (2nd Mac address). The recipient then opens the package to find his name on it (his IP address). Hope this helped and not confused anyone.
