Proff.Kurose This is Great! I'm in a networking class right now and this is by far the most instruction has "spoken" to me. I really like that 1) your not regurgitating the book. 2) and this is huge for me, you provide context to the concepts...Also enjoyed the Fire side chat by Vincent Cerf.
Internet Protocol (IPv4) and Addressing Basics 00:11 The Internet's network layer is covered in two parts. 02:33 The Internet Protocol controls data formats, addressing, and packet handling conventions. 07:19 IP addresses identify link layer interfaces, not hosts or routers. 09:44 Each subnet contains devices that can directly reach each other. 14:55 DHCP clients server message exchange 17:34 DHCP message process overview 22:07 Address allocation, forwarding table lookup, and BGP routing are tied together. 24:40 ICANN administers and allocates the IPv4 address space. 28:59 Internet Protocol started with a 32-bit address space
In the DHCP part of the video: Why is the transaction ID incremented after the OFFER? RFC 2131 states: "The DHCPREQUEST message contains the same 'xid' as the DHCPOFFER message." I guess you could use any transaction ID for the REQUEST / ACK, and there is no reason, why it wouldn't work. But what purpose does it serve to change the ID? Does it help with possible collisions of ids in a larger network?
I think it is because some clients can skip the DHCP Discover and just go straight for DHCP request (for example when a client wants to renew an IP it used previously on the network, etc.); so, a new transaction id pops up. This is my understanding, and I could be wrong for sure.
Kurose and Ross book is already like the Bible for us. So happy to see the RUclips series. Thank you Prof. Kurose
How do you study the book? What is the process since there is so much information. I can see that you use the book and the book
"Something doesn't quite add up there..." Hilarious! Great lecture, thank you.

Splendid lecture sir. Thank you for all the effort put into this!
That's quite interesting how Internet is evolved from back into the times to which we are seeing now.
That's really a awesome lecture. Thanks for making learning easy.
The lecture was excellent, with instructions that were both clear and concise. Thank You, Professor!
The ending quote is fantastic
this is really good explanation, just brilliant
Wonderful lecture, thank you :-)
Thank you for explaining sir it is awesome
Very nice video, good explanations!
Thank you Professor 😊
2:50 spitting facts
How subnets length gets fixed ?
Like knce its 23 and 24 ?
Thank you so Much Sir
