[@abrhammamuye1361]

Thank you very much for helping me in understanding all over complex courses of computer science. I'm really happy and lucky to have you throughout my learning life.

[@macvisys7127]

Sir your lectures are amazing i just kept watching like webseries..... First time this has happened with me... Brilliant teaching! 👍

[@LofiVibesRadio]

I wish you were teaching in my University , Thankeww so much sir for sharing so much of knowledge Absolute grateful to you ;)

[@ArthurCor-ts2bg]

Good job... Your videos extremely interesting... Keep it up

[@yashnani1178]

Tnq for your lecture sir now i totally understand about classless and classfull subnetting tnq so much.........

[@prashantdiwakar1302]

No one better than you in cs sir

[@issiagadiallo3684]

Excellent !!!

[@bhargavdobhal5327]

CFBR🔥🔥🔥🔥🔥

[@munmunchowdhury9729]

awesome lecture ....

[@arjunkhanna1803]

sir suppose a device A has a perception that device B is in same network & thus A will send message/packet to B directly but in reality B is present in another network than A. then how can A send packet to B directly??

[@sangeethar5357]

excellent!!!

[@louerleseigneur4532]

Thanks sir god bless you

[@GATEVeteran]

what book to get in depth knowledge of this concept?

[@harshalthanekar4397]

IPV4 packets IPV6 packate ?? Is it explaned further?? Or it is not important for competitive exam mcqs?

[@karthik-ex4dm]

at 15:00 how will B know the subnet id of A???

[@pratyushchakraborty7529]

Thank you Guru Ji aap acha samjhate ho

[@pradeepagarwal1962]

Great sir

[@sarthakgupta1263]

great lecture...

[@jateenkashyap2365]

255.255.255.255 gives 2^8 subnets in class c network.255.255.255.0 gives 2^0 i.e 1 subnet or the same network.

[@sibinthomas9681]

This may be a simple question but i am confused. Why does my computer need a subnet mask, after all subnet mask is required by a router. ?

[@ankanbhattacharyya8805]

subnet mask in machine is required to know the ip of the Router.

[@vivekaluru363]

@@ankanbhattacharyya8805 not ip of router...its ip of n/w

[@retsvus]

Subnet mask on PC tells TCP/IP stack whether traffic destination is local or foreign network. For first case, packets sent directly to target. For second case, routing table (netstat -r) must be checked to send packet to Default Gateway (on router)

[@himanshuupadhyay3129]

Every host is supposed to have a subnet mask(even though it is not a router) so that it knows whether to send packets to a default gateway or to destination in same network.

[@ashishmehtaofficial23]

sir please its my humble request plz post the video of Transport Layer... I need this one.. my exam is going to start in April...!

[@sunnyjain630]

meri b yr.....

[@anonymousa6070]

ho gaya exam? kaisa raha?

[@shubhamgupta2794]

How to get full course

[@ShivShankar-ut4ul]

one day paper preparation kit

[@shwetabhshekhar9134]

plesase upload the video on routing algorithm .plz sir

[@kshitizmohan620]

HOW WE WILL DECIDE THE DEFAULT SUBNET MASK FOR A CLASELESS IP?

[@aishikbasu2291]

How does B have the subnet mask 255.255.255.192 when its ip ends with 69? even with 4 parts it should be the subnet mask should be 255.255.255.64

[@biggbosspromo8575]

AND the subnet mask with ip add of B.You will get this

[@KumarGaurav-ty5nw]

if A wrongly thinks that B is present in its own network (but B is not present in its own network) and send the packets directly to B then what will happen??

[@vishalupadhayay8131]

THen packet will be send to router and router will forward it.!!

[@ekta1917]

at 26.29 Question->DBA 200.1.15.2555(given). Calculate network id and subnet mask. As it's class C (Directed broadcast address ) . So, 11001000.00000001.00001111.[1[1[111111 From last 8 bits HID must start , can't start from 3rd octet. Am I correct

[@neerpatel4647]

I had doubt ,,, in the example that you are explaining at 17:41... you told that network-A has submet mask of the 255.255.255.128 and it's network id is 200.1.2.0... then obviously the all the IP addresses from the range of the 200.1.2.0---126 will be in Network-A itself... then how come IP address of the network-A can go in the IP address of the network-B ????????????

[@vaibesb4u]

Coz Ntw B is merged with N/W A both have different SM and NTW A is larger than NTW B in this example

[@nomad_diaries86]

sir can u pls explain how n/w a is larger than n/w b

[@shreyaswaghmare7690]

21:00 - A can send a packet to B directly thinking that B is on the same network. But in reality, B is on a different network(so A should not be able to send the packet directly). Isn't this a contradiction?

[@deepakkar2011]

Shreyas Waghmare if A arrives on a result that A and B are in same network then they are definitely on the same network in reality. But as B arrived on result that A and B are on different network then there is a possibility that it is an illusion

[@ankitsrivastava7363]

good

[@nomad_diaries86]

sir can u pls explain about subnetmask 255.255.255.0?

[@igniculus_]

You are in a class C network. anding it with your IP will give you many information as he explained

[@shailendrasahu5030]

can anybody plz explain this Question. Q. Ip address in the range 186.220.64.0 to 186.22071.254 are kept in a VLAN The correct netmask so that messages are broadcast only within this VLAN is a) 186.220.255.255 b) 186.220.248.0 c) 186.220.248.255 d) 186.220.8.0

[@GATEVeteran]

invalid range

[@GATEVeteran]

taking 186.22071.254 as 186.220.71.254 i calculated it as c) 186.220.248.255

[@vaibesb4u]

255.255.224.0 SHOULD be the SM

[@madhavreddy6314]

considering the given n/w is of classful classification,it belongs to class B and in class B NID is of 16 and HID is of 16 bits and sm contains 1's in NID and SID ...as you didnt mentioned the no. of subnets considering the entire n/w the subnet mask will be 255.255.0.0

[@sibinthomas9681]

my Subnet mask is 255.255.255.0. Am i special???

[@satadhi]

nop u are a class C person
