You were awesomely blessed with the skill to simplify Networking concepts to a simply point anyone can properly understand. That’s a radical skill in simplification of concepts.
Bravo! What a useful video. I learned about different representation of the MAC addresses in operation systems and how to see my computer's MAC address on the powershell using the appropriate command. Keep this well and compact lessons
I've commented before on this series. But the quality warrants a continued appreciation. As a career data architect & analyst, this series has cleared up so many questions about how networks work ... things I previously just ignored. Keep up the great work CBs!
So MAC addresses are the physical device identifiers given to each device to identify each device connected to a local network. When accessing the internet, sites may also access your MAC address to determine what interface to provide to you (windows/Mac etc).
Could anyone explain to me how does MAC address differ from private IP address? I thought of MAC address as a local way for communication whereas IP is a global way for communication, but with private IP addresses, MAC address seems redundant to me.. thanks in advance
Hello, thanks for the video. Why a router assigns an ip address to the devices within the lan ? Isn't the MAC address sufficient to establish LAN communication ?
If I have comprehended correctly, it's because when talking about the communication in the layer 2 (a switch between nodes and under the same network) you must use the MAC address. The IP address comes in when a node want to communicate with the node that is outside its network which means it transfer from communication between nodes under the same network (using MAC addresses) to communication between routers (using IP addresses), and after the data has transferred to the destination network, it will return back to communication between nodes under the same network (using MAC addresses).
I came here because I had a suspicious Mac address connected to my wifi for quite some time and thought its my own devices. I had block the Mac address today hope everything will be fine. I want to know how to trace the mac address from where they connected.
Soooo I am trying to find out how to find the MAC address Destination and Source on Wireshark. But am not sure how to find it. I also need to find out the NIC manufacturer Source and destination, as well as the NIC serial number for destination and source. any clue on how I can figure this all out?
Like, i change my MAC adress because my mom is turning on Wi-Fi control, can I..like.. change tha MAC address to another one, and then change it to the old one?
Why do we need MAC address at the first place? IP address is unique in a subnet. Can't switches be configured to use IP (as a unique identifier) instead of MAC address?
I still dont anderstand the consept of uni/multi/broadcasting using MAC adresses ! How can we unicast to a device by specefying a mac address with the least significant bit in the first byte is set to 0, and yet .. mac addresses are always fixed ! That means that a device can be part of either a multicast or unicast based on that specefic bit in its nic burnt mac address !!
Great question. Hexadecimal goes in the below order. 0 1 2 3 4 5 6 7 8 9 A B C D E F So to answer your question, 0 is the lowest and 1 is lower than A.
Private IP addresses can be changed and you can have duplicates. MAC addresses are unique and are 'burnt in' to the NIC. This means computers can communicate even without an IP address, for example, when using DHCP.
@@Certbros I did not forget. When I hit enter it didn't recognize it....I had to hit space in between to make it work.. you did not teach this properly....typical
@@Certbros Yea cuz when I first typed it in....it wasn't working....I was like what?.....Then I had to figure out that it was the "space"....initially I typed it as one word. It's still a good video.
