6 years later and this video is still much valuable

[@gurdeepmundi6440]

this video should be on the top of the search results.

[@michaelivanhaileka9694]

on the top is just videos in Hindu...so frustrating

[@Sauce-ke]

it is now

[@_Anna_Nass_]

I have ADHD and it's hard to keep my attention. I have been watching your videos for 30 minutes without pause, genuinely interested. That's amazing. Thank you.

[@TwoWarPlayers]

I have ADHD without the H, trust me IT is a great field to be in with ADHD at least for me.

[@MahmoudSobhy]

Thanks for watching!!!??? Thank you for explaining it in a way that is simply awesome.

[@rishmael21]

I’m actually studying and currently taking the SANS GCIA course. I must say this video is spot on with the breakdown of the IPv4 header!

[@f8881f]

Awesome explanation 👍

[@showaibatwork657]

7 years later and ipv6 is yet to gain popularity

[@biscuit5973]

As simple as but u have explained the TTL thanks

[@KevinMtutoriales]

Finally a good video explaining this header, thanks Sr!

[@perkerteller9868]

What do the numers mean above the different parts?
and another question: in my book there is the sentence :
IHL (4 bits) : Internet Header Length (in 32-bit words) and the minimum value would be 5???
what does this mean?

[@boca-sama]

Decimal value of IHL to be minimum 5, so in binary it would be 0101.

[@rishmael21]

5 pertains to the minimum value you see in the hex of the packet in the offset 0 position as indicated by the header length. 5 must be multiplied by 4 to get the size of the header. 5*4 = 20 bytes.

Saved my life. Easy and understandable👌

[@BlueKaiTheEnd-]

Excellent video!

[@raihanteaches1742]

Very nice explanation

[@josealfredoperezlorenzo1727]

Is it possible to transmit voice in real time over the internet protocol, yes, no and why?

[@raulsanchez4716]

Thank you for explaining.

[@Vishal360]

Simply perfect ✌🏻

[@fithazainabzakkeer1570]

Thank you for this video Sir

[@markuswerner7271]

You have an example?

[@alexla2962]

very informative thanks for posting

[@srujanavvl]

Thanks for the Video :)

[@exitedtolearn8458]

I have a question does the protocol only tell what protocol it is or does it also tell the tcp port?

[@hmdz150]

The TCP port (source and destination) are defined in the TCP header (the payload of IP packet)

[@Nachodood]

Thank you very much! So helpful

[@NoOne-uz4vs]

Great explanation and most importantly: an AMERICAN ACCENT!!
Thank you!!

[@ibrahimnabil13]

thanks this helped me so much

[@clasesutnfrc8699]

02:55 Differenciated services or Type of service

[@juliabaker7517]

very clear explanation!!!!

[@burstfireno1617]

thank you

[@daniiltimachov]

Fine. Clear. Cool.

[@valentinionita4798]

I don't get it. Why you never include MAC Address?

[@naserintegral]

The guy is talking about layer 3 of the OSI model, MAC addresses are at layer 2 of the OSI model

[@hmdz150]

MAC address is defined in the frame header in layer 2 (datalink layer) of OSI model

[@usamaluqman2494]

thanks

[@kyliestaraway2492]

Is it the maximum 64 and not 60?

[@yoyo-gv8zs]

i think 64 is for the ethernet frame Kylie no Jennar though u get me? regards from London

[@kodandaramravipati2959]

thank you sir

[@taddy666]

thanks so much

[@ANISZARTI]

thank you sys-eng 💚

[@manishthakur671]

Thanks a lot

[@TheSimplyJJP]

IP addresses are 32 bits not 31!

[@hmdz150]

It all starts from 0 in IT ;)

[@siddhu6661]

Thank you senpai
