- Correction !!!: At the third step (5:52s) , the destination IP address should be 192.168.1.50, which is the server's IP address. Sorry for my mistake.
Today's topic is ARP. What is ARP? Why do we need ARP? How often do we use ARP? How does it work? This video would answer all these questions.
This is my education channel. My topics cover networking, security, programming, and other computer-related materials.
Please subscribe my channel. Many thanks.
You deserve 1000x more subscribers, thank you for the informative lesson!!
thanks.
i too can't believe i get the concept in one go. the explanation is simply concise.
It is amazing that by watching your videos on ARP, subnets, and IP addresses "I got it"! Before I found your videos I literally spent two days trying to figure out what my instructor (by video) was talking about. Thank you for making it simple, fun and memorable! Great job.
Great to hear!
Sunny, You're a great teacher. Thank you so much. I just wanted to express my appreciation.
You are quite welcome, Pixel. I appreciate your comment. You are very polite.
@@sunnyclassroom24 I'm in class for TCP/IP right now at Denver University. The videos help me understand the assigned text so much easier. Your videos also give me the appropriate foundation to appreciate the text and how it may help me in the future. Saint Mary, Leavenworth of Kansas is very lucky to have you for an instructor. I think I speak for all of your viewers. Thank you again. Please keep it up.
@@pixelmartyr8532 Thank you very much for saying such nice words about me and my humble videos. I appreciate it very much.
Super Teacher!!! You are a 💎 simplifying networking concepts. Thank you 😊
@@sunnyclassroom24 @2:32 ...physical address is the MAC address bruh🙄
Thank you sir for sharing your knowledge, with the easiest English language I have ever heard. You speak English better then English people.
I'm so passionate about your videos, I can't stop watching them. You explain things very well. Thank you so much teacher
Thank you Mr. Sunny, for simplicity, clarity and to the point method of teaching.
ARP is a layer 2 protocol because it's only use layer 3 information (i.e ip address) and fetch MAC address (i.e: belongs to layer 2) from corrisponding machine for establishing the MAC/ARP table. So IPs store as a reference here and all communication is going through the MAC on LAN. Sunny your classes are very helpful to understand the topic in very short time.
You videos and way of explaining things is brilliant!! I can't thank you enough.
Best IT educator I have encountered on CZcams. Thank you for your clear and concise explanations!
Aced my TCP/IP class. I'm a changed person coming out of it. Thanks for your help Sunny. I will keep watching your videos and always recommend you. Thanks again.
Thank you very much!
I want to thank you, I couldn't get this so clean until now! Thank you from MX
You are welcome!
good lord .. i am suddenly beginning to get excited and love networking much more. your real-life examples are so real basic and realtime that it is easy to connect the lesson to a life examples!! that is amazing. God bless.
Great to hear!
I feel like this is one of those protocols that don't really fall into a specific layer. And as you said, it could be a "2.5" layer. But if I really had to pick, I'd pick layer 2 since the communication happens within the LAN and not from one network to another.
Great Video!
you are correct since it is happening on layer 2 (MAC address requirement). It might be more correct if it is more layer 2 than layer 3, it is 80% layer 2.
This is so easy to understand. I finally got it. Thank you so much for explaining this topic THAT simply and for sharing this. You're awesome.
You're very welcome!
Hi Sunny. Thank you so much for your simple way of explaining such a vast and complex subject when looked at for the first time. Now....what do I think ARP should be? I personally would feel it should be Layer 2. Why? Because it makes it unique for a LAN not a WAN/Remote Network. ARP is for having a conversation with people in the same room where IP is for talking to people in the next room or by phone to the neighbor down the street or to a friend in another state or country.
Man, you explain things extremely well, thanks for the video!
Your lessons are so great, much better than my "professor"! Looking forward to more! Mercie!

Best Virtual Teacher! THANK YOU
Come back to San Francisco professor Sunny ☀️☀️😎
Simple and well understaned....thankyou sir 🙏
I have seen your all videos..its awesome buddy..u r so.good...please make scenario based questions on Cissp topics..
A media access control address (MAC address) is a unique identifier assigned to a network interface controller (NIC) for use as a network address in communications within a network segment. This use is common in most IEEE 802 networking technologies, including Ethernet, Wi-Fi, and Bluetooth. Within the Open Systems Interconnection (OSI) network model, MAC addresses are used in the medium access control protocol sublayer of the data link layer. As typically represented, MAC addresses are recognizable as six groups of two hexadecimal digits, separated by hyphens, colons, or without a separator.
Heyy, You are awesome. Thanks so much for this vital information in most simplified way & effective presentation.
You're very welcome!
i watch your video playlist whenever i have tome and increase skills. Thank you Sunny and if you please make cyber security topics videos series would be helpful.
Thank you Sunny. In my opinion ARP itself is Layer 2 since fundamentally it's not doing any IP forwarding.
thank you so much Mr Sunny, you are doing a great job that some selfish people wouldnt wanna do
Thank you very much!
Your lessons are gold. Many thanks!
My pleasure!
Awesome Video.

Excellent stuff, Sunny. Question: How does the client know about the existence of the server? Where does it get the IP?
nice tutorial. thanks
You are good coach. Love your video.
Thank you so much sunny! very informative and understandable
you are welcome! thanks a lot for your encouragement.
my best teacher sunny thank you very much , 100 like
You are the best...Thanks alot
What a great video professor! 💖
Many thanks, Arpit!
Excellent
Thanks Jian Yang.
You are welcome
Hello Sunny! thank you very much for the high quality videos. When any computer on the network send an ARP request, the ARP cache on all devices get updated with the requesting computer information?
Excellent!
Sunny you really rock at this. I just would like to know how can an ip address (layer 3) be inside of a Mac address (layer) in this ARP broadcast?? On my understanding layer2 can only carry on layer2 addresses (Mac address) . Thank you again Sunny.
Your analogies like the name and address, help me to understand more.
I watch your videos on 2x speed.
Still able to understand.
Thank you. Very well explained
Glad it was helpful!
Your videos are awesome!
great work thank you! I would like to ask you to upload one video about ARP Protocol TYPES if possible, looking forward to seeing you on next video thank you.
You are welcome. I put your request on my to do list.
@@sunnyclassroom24 thanks for considering
you are awesome sir. thank you.
Can you explain in details, under the data link layer, the loop-back interface concept in relation to MTU? Also, what differentiate the dynamic from the static statistics when you run the cmd arp -a?
thank you.
This is excellent
More videos pleaseeeee! Love you Sunny
Many thanks sunny
my teacher told me ARP is layer 3 protocol because ARP involves layer 3 IP address
I'm not sure if you intended it, but I laughed at WhatsArp
Thank you for your laugh.
lol, humour doesn't come cheap
Yo what's ARP?
It is always a bright day whenever I come to Sunny Classroom! Wish I had you for a teacher when I was growing up. You make networking sexy again! It is short, sweet and very informative!
Thanks for watching! I appreciate.
Sunny you are amazing!

Sunny YOUR THE MAN
Thank you for watching!
Great!
thank you so much , great lessons
Glad you liked it!
BRILLIANT!
Thank you sunny for the class. But I have a quick question: why does the host know the iP address of the server but not the mac address? Thanks again
Really useful video...
💯💯💯💯
Thanks a lot.
