    Thank you for the final question , i learned a lot during to find the answer. Well what i found is : Question was for R4 network , so before it we have R3 wich is 192.168.5.192/28 in this case its broadcast id should be 192.168.5.207. The R4 network must to start after this , wich is 192.168.5.208 ( Network ID ) , the best possible host number was " 15 " for requested hosts , that means Broadcast ID is 192.168.5.223 . Host Ip range would be then 192.168.5.208 -> 192.168.5.222 . Since we borrowed last 4 bits from last octet , there is 8+8+8+4 left and that gives us the prefix /28 CIDR. And ip was also Class C ( yes VLSM is classless but.. ) so the remaining "1"'s ( 128+64+32+16 ) telling us that the Sub Mask is 255.255.255.240. i hope thats correct.

      Hi Evren Ersoy,
      You are partially correct. The possible host was 16 that is 2 power 4. The first address is always network and the last address is a broadcast address. I can see your network id and broadcast id are correct but the host range starts from 192.168.5.209-192.168.5.222.
      Thank you

    Nice tutorial. I noticed you count from 2^1 instead of 2^0.
    2^0 is included in the 8 bits. 2^12 is 13 bits making 5 host bits on the second octate from left.

      You really helped me out and I got a B at a 76% mark in the overall subject.
      The low score is because I did /29 as the subnet for the WAN instead of /30 subnet, this was a dumb mistake on my part XD

      On every router, we have used two ports (S0/1 and S0/2). So for three routers, we need 6 IP Addresses. Hope it is clear.

    • @GabrielTobing
      @GabrielTobing 3 роки тому

      The part at 6:22 is where it is at.
      Basically, when you are trying to find the network side, you will do addition of the 2^n values.
      For example:
      In this octect, we have 128 | 64 | 32 | 16 | 8 | 4 | 2 | 1, all of which are 2^n results up to n = 8.
      The IP 172.31.0.0 has 4 octects.
      The 172 and 31 are the network octects and the two 0 values are the host octects as we are in class B.
      When we are calculating the host, we calculate it from right to left. To obtain the hosts, we had to use the 2^n, and with that, we have had to use up 12 bits from the right side.
      To obtain the 15, what we are doing is counting from the right side to the left side with the values of 2^n for all that we require to obtain the hosts.
      So the following would happen:
      8+4+2+1
      Adding that is equal to 15, and hence is how we get to 15.
      I hope this makes sense :D

      Thanks for your feedback but the video is right.
      The number mentioned in the grey box are the value of binary bits. and the number I have mentioned in the green box are to find the number hosts. as we know that the formula for finding the number of host is 2^n (n= number of bits reserve for the host) e.g. If there is 7 bits reserved for the host = 2^7=128.
      I will recommend you to watch my subnetting video first. Here is the link: ua-cam.com/video/q7wNcYliJ1Q/v-deo.html
