  • OK now if I can just remember this on test day. Everything in CISCO is a trap.

  • Great, you just taught me that if it seems too easy.. It's probably a trap.

    Thanks and very nice explaination.

  • I may have to view this again but a very nice explaination

  • He's is wrong because if the he is has 28 bits on and 4 bit off.

    2^4=16 hosts

    2^4-2=14 usable hosts

    11111111.11111111.11111111.111­10000/28

    Then the first usable host in that is ip-address range would be 225--238, not 224 is the network.

  • @icykid Oh ok, Thankyou.

  • @kevrev7 he didn't say that was an actual address for a host he said thats the address space for the subnet so 224 is correct

  • your answer is wrong! Its a network address.

    0 -15

    16 -31

    32 - 63

    64 -95

    96 - 127

    128 - 159

    160 - 191

    192 - 223

    224 - 255 You see over here. Your 224 is being used as a network address. Tell if I am wrong, But I think Im write. Your answer should have been at least 225 or 224. Because you cant use network or broadcast addresses when subnetting.

  • thank you!

  • Man you are doing a great job! I cant thank you enough...

    I´d like to know the name of the software you´re using to record your screen?

  • this is very helpful on how to recognize VLSM issues. Thanks
