MAC Address Explained

- What is a MAC address? What is the difference between an IP address and a MAC address? The MAC or media access control address is an identifier that every network device uses to uniquely identify itself on a network.

well done...thanx
Identify a device, like what ???
How can we send you a email ?
I'm confused a little. Say the Google web server sends responses back to the source how will the router know which host to send responses if MAC addresses swap from hardware to hardware? On top of that the IP address is translated from private to public and vice versa. How does the router determine which private IP made the requests?
When two hosts in two different networks want to communicate do they use private or public IPs?
You'll not find such explanation in schools/universities,
Great video as usual
Thanks! 😃
Agree
Because they don't have animation facilities
@@Urjnot Well, then it's a shame that an individual has more facilities than a school/university,
In my opinion I think they can't give what they don't have (i.e. enough knowledge or teaching skills)
I totally agree with your statement
I went to university to study IT and I always felt super dumb (I failed the very first year lol), could never understand networks. Now, I am taking a cybersecurity online certificate and I must say, I understand it thanks to YOU!!!! I can't express how grateful I am for your videos, I finally get this!!! thank you so so much
One minor point. While MAC addresses are supposed to be unique, this isn't always so. Some manufacturers have been known to reuse them. Regardless, since MAC addresses are relevant only on the local network, this is usually not a problem. With IP, the MAC address is discarded at the first router and replaced with the MAC address of the interface on the next hop, etc.. Also, there are some links that don't have a MAC address. These would typically software created links, such as VPNs. The router only has to know how to reach the next hop and that can be designated by just the interface.
wow, Thank you so much for your explanation
thank you
Extra note: with the additional usage of virtual machines, VM kind of cloned the physical card and provide you with an "additional MAC address". On a side note, you can actually spoofed your MAC address on some NIC (commonly used in packet injection for WIFI hacking). In such scenarios, MAC addresses can actually be not unique.
Right, they also usually take the duplicate MAC address NICs and ship them off to different parts of the world, so there's even less of a chance they'll ever meet in a single network and cause problems.
waowww this is amayzingggggg wooooooooo
As an engineer, I really like your videos and how you explain these topics! I often recommend them to our newer employees at work since their base education from school often leaves a lot of gaps in the fundamentals they need.
Thanks
To this day i always go back to PowerCert for a recap.
Yeah, these are pretty good. I've been a software developer for 25 years. Never had to bother with this but now I need it and it's a struggle!
U are an amazing person God bless u
I'm new to IT and have been taking courses to transition into this field. I wanted to express my gratitude for the time and effort you put into these videos. I am a visual learner, and these have been so incredibly helpful to me. You break things down so clearly! Thank you for helping us IT newbies not feel so intimidated and lost :)
I agree with you! I just started to learn about this field, and I was a little confused. I was so happy when he gave us a demonstration with the address and name. It seriously clicked in a second.
Love all your videos, perfectly explained
Hi
Thank you so much sir, we are going over this topic in my collage course right now so this not only helps me understand the concept but also gives me more info than my professor does. Thank you so much!
You really have a knack for teaching, those analogies and "now you might ask"s are so on point and drive everything home clearly
Your're one of the best teachers on the face on the planet, in my opinion. Thank you and may you live long enough to bless us with your teaching abilities.
Best teacher I came across for 40 years
Thank you for making me feel smart because the way you simplify things
agree..
Your videos are the best. You explain very clear and straight to the point and you explain in a very simplistic and understandable fashion. Thank you!
Seems you are revisiting and doing the videos more neatly than before. Incredible! Thanks a lot for your great effort. Always eagerly waiting for your videos.
You should get the highest award for teaching in all over the world.
Really really appreciate your hard work.
Your videos are awesome. Explained in a way that is super easy to understand. Thanks!
I so enjoyed your explanation about MAC and IP addresses that I had to pause the vid in order to have made this comment. Your explanation is detailed and accompanied by real life illustrations that make learning easy to understand.
Thank you infinitely for the clarity and simplicity with which you explain the course. It makes learning so much easier and enjoyable! 🙏😊
dude, you have answered my questions in mind. none of my college professor would explain this to me
08:12 So, I wanna thank you for uploading this video, as I gain more knowledge watching your videos than my entire my time in college 🙏
Glad I could help!
Thank you great refresher! Love your diagrams! It really brings the concepts to life!!
I'm literally using your videos to build up my foundation in IT in my Bachelor's studies, thanks!
Sir, the word " thank you " is not enough for the amount of effort you're investing to teach every people around the world by making these type of videos. I really wanna thank you from the bottom of my heart. I'm from India and your Channel has a very big fan following here ❤❤❤
Thanks again, this channel is one of the best on TH-cam
The amazing part of all of this MAC addressing hop-scotching over the internet to find that Google server is that it all happens in milliseconds.
this! Seems so slow here but happens so fast.
Excellent video, finally i understand the use of both IP and MAC individually and how a network uses both to comunicate
Thanks for this great explanation, it helped me on the interview for school (it's an IT school with a paid practice so it's half school and half job), interviewer was excited when I explained it to her like in this video. Your videos are amazing man💪
What an explanation, I'm studying Cybersecurity at School and none of these has been taught to us in this good, thank you A lot for these amazing videos
Really awesome videos , super educational and helpful ! I have just stumbled upon this topic at school , and you basically read my mind!
This is an excellent video. No one explained this quickly until now.
Awesome. I really appreciate how simply you are explaining these topics.
Great content! You do a great job of simplifying these topics. Please keep it up.
Well done sir. You solved my question about how IP and MAC work together. Really appreciate it.
Man, this is crazy, you have just summarized in 8 mins my whole first networking university course! You are the best in this on youtube
Thank you :)
I've spent a lot of days understanding these concepts, but failed. Such a great video.
Thank you very much. This explanation was thorough and made it easier to comprehend the path data takes on a network.
Man I love this channel and this video was great as a lot of others. It cleared up some fundamentals for me.
Great video, thanks for explaining the different MAC addresses there at the end for the Wi-Fi adapter and the Bluetooth adapter and the NIC
i watched many videos on many channels today, and they were all good, but yours is by far the best, very simplified and organized . it kept me focused and drilled the info in my brain. you earned a subscribe . from now on i will call you sensi :D

I legitimately thought a MAC address was just an Apple product using the network (I.e., MacBook, Ipad, IPhone, etc.). Thank you for these videos.
Next time i write someone, I will indentify myself using the M.A.C address and I.P address 😂
Your videos are cool! Easy to follow
Outstanding. Very clear and useful explanation. Thank you so much!
