    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??

    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.

    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

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

    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
      @ankanbhattacharyya8805 6 лет назад

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

    • @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
      @himanshuupadhyay3129 5 лет назад

      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.

    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

  • @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??

    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

      taking 186.22071.254 as 186.220.71.254

    • @madhavreddy6314
      @madhavreddy6314 7 лет назад

      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

  • @neerpatel4647
    @neerpatel4647 8 лет назад

    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
      @vaibesb4u 7 лет назад

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

  • @shreyaswaghmare7690
    @shreyaswaghmare7690 6 лет назад

    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
      @deepakkar2011 6 лет назад

      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
