MicroNugget: What are IP and MAC Addresses?

[@alexanides7257]

I couldn't figure this out in a 3 hour class and just learned it in 6 minutes thanks to this video. thank you

[@minkiesukad2104]

exactly!!!!!

[@joshbowman7114]

Right!? Like, "Hey Teachers! Take some notes because this guy knows how to teach." :P XD

[@spyrostom7156]

You are talking extremely fast!

[@gabi66gabigg]

speed 0.5, trust me it's great

[@abrilbarrera2680]

He explains very well though and since this is youtube and you can reply it as much as I want, I am really happy with this.

[@ardentdfender4116]

the_G_thing It is quite funny 😆 at that 0.5 speed. At 0.75 speed worked for me.

[@zozoalaa6661]

just try it with speed 2 .. it is so funny :>>>

[@MI-lo2hj]

[@chaaacha3762]

That's the greatest explanation I've ever herd ❤️😍

[@wakeup9557]

Thank you so much for actually answering this question!!!!! I have been searching the internet and watching videos for the last two days trying to find someone to explain why we need both a Private IP address and a MAC address.

[@decus9544]

Excellent explanation and much faster than a lot of the more laborious, wandering explanations that never actually get to the point.

[@haow9020]

Why, in the two-address case, don't we use two receiving IP addresses -- one for the router, and one for the destination -- when encapsulating the data? (Then again we can do without the MAC?)

[@cbtnuggets]

Hao Wang Great thought! ... but that's not how they built it back when the powers to be created networks :o). Keep in mind, we used to live in a world where there was more than just the IP protocol (there used to be IPX, AppleTalk, DecNet, and more). They all relied on a mechanism similar to this to communicate.

[@haow9020]

CBT Nuggets What about using (one or multiple) MAC addresses? We could have avoided introducing all the protocols like IP/IPX/AppleTalk, etc., and based all communications on physical addresses -- Do you think it's a reasonable idea? Thanks for your response.

[@cbtnuggets]

Hao Wang Perhaps network communication could have worked this way. Thanks for the insight!

[@mattgirschick1902]

CBT Nuggets THIS is what I've been having a really hard time to wrap my head around; It seems counterintuitive. What you're trying to say is that it's this way for no logical reason but because it was necessary to the evolution of networking? Kind of like a patch?

[@rigelr5345]

Finally a proper explanation that doesn't just cover the mere basics. Also I almost always speed my tutorials up to 1.25 or 1.5, didn't have to this time, so I really didn't mind you talking fast (also, people have the ability to slow videos down too lol). Anyway, thanks.

[@cbtnuggets]

Great! We are glad you found this MicroNugget beneficial.

[@pavelsavka1476]

OMG, you explained it so GOOD, yes it is fast but to be honest it was 100% clear for me what you were talking about. And i am native Russian speaking person, Learning in DUTCH university. And your videos is as clear as light. So you don't need to go slower, otherwise it would be to boring to listen, and to long. Good job! thank you

[@minkiesukad2104]

F...-ing hell, i have been looking for a clear explanation like this for 2 days. Thanks very much!!!!!! (talking speed is fine, don't worry about the comments)

[@vladimirzaikin5316]

Really love that video!!!! Lots of thanx to the author

[@cbtnuggets]

Vladimir Zaikin, thanks for the feedback!

[@osamaalzen2080]

I spent 3 hours reading without really understanding what the heck was happening, and in 5:41 seconds I understood it all. THANKS ALOT!!!

OMG! Extremely fast but extremely good and easy to understand! THXs

[@cbtnuggets]

Thank you! Glad that you found the video helpful! :)

Love the passion you put into this, thanks a lot!!

[@amirhosseinkhodami762]

that was a REALLY BIG QUESTION in my mind, Perfectly Answered thank you

[@haimbendanan]

Awesome video, helped me understand the topic much more than reading from textbooks. Thanks!

[@harry09_08]

thankyou very much!!!! bit fast ,but atlast made an effort to understand completely in ONE HOUR by pausing the video at different points !!!!;)

[@Lawndre4ya]

How do I go about changing the network id part of my ip addresses on my network I need them to be different

[@kanchanggogoi7250]

your video is really helpfull..But if you deliver it little slowly,it will be much effective for the candidates.

[@iflnr978]

Thank you for talking fast. My personal preference is for getting to the point. While I don’t understand totally, I have the option to REPLY this video. I watched 3 videos on this topic and this is addressing my lack of understanding most directly. I don’t like listening to slowed down, dumbed down, repetitive explanations, thanks not only for explaining the ‘why’ but getting to point If you want slow repetitive dumbed down content search Linux Chris Titus Tech

[@akhilvenkateswaran4965]

Is mac address mainly used for ethernet connections???For tcp/udp, dns is used for the above purpose right??(mapping domain name into ip address directly)

[@SAR2325]

Holy shit! I've been studying for the CCNA, and I-in all my hubris-thought, "Meh, I don't need to watch this video, but it's Jeremy, so why the hell not?" I understand so much clearer and simpler now something about which I thought I would never need further explanation. Also, 1.5x speed doesn't let you get distracted :)

Wow! Romani peste tot. Bravo, Jeremy :)

[@suhaaskorampally]

Hey, can you explain me whats the problem if you just send the IP of cbtnuggets.com to the router?

[@tarek6291]

There is no problem. You can ping the ip or access the http page directly from a browser if you know the ip of cbtnuggets.

[@leandrawoods8568]

From what I understood, I believe you can't send two IP addresses at once... So, you first broadcast the router's IP address and the intended router sends back its MAC address. The source then sends the final destination's IP address to the said router using the received MAC address.

Great way to understand!! Thank you! :)

[@reeceytaylor]

So... the 192.168 is like my town the .1 is like my street and .1 is like my house number. And then the MAC address would be me? And if I wanted to send a letter to someone on the otherside of the world I would have to send my letter to the letterbox (router) so then the postman can deliver that letter to that someone on the other side of the world?

[@TheHimalSamarasekara]

Superb.. thanks

[@navekeinan]

this is such A great explanation :)

[@nikhilmudholkar2769]

awesome video. This video just cleared all my doubts.Just one doubt. You told that initial part of ip address represent the network part. I just saw my router and it's network part also had same ip address i.e. 192.168.1 . Now my network and your network are different. Then how come they have same part in ip address?

[@timjackson7343]

Goodness, He sure is a fast talker!! Think I might need "Computers for Dummies" to learn what's the difference between IP and MAC addresses?!?

[@NihongoGuy]

And the scales fell from my eyes.... Why does every textbook/course/instructor make this so hard? I think it's because they really don't understand it, but you do, Jeremy.

[@sukanyachauhan9653]

It's excellent. I have a request, can you say things bit slow. I am not so proficient in English. It will help me to understand the concepts better. :) Thanks

[@lileli12]

finally what I was looking for. this video is fucking awesome.

[@RoyalTurmoil]

Ok. So: the MAC address is the network? Aka router/server.. And the IP address is my computer?

[@dombloggs]

Chubby King No Mac address is kind of a serial number of your device (network adapter) and IP address gives information of the network.

[@suyogtate4231]

Thank you very much ! that helped a lot , little slower would have been appreciated :)
