    sziasztok,

    Kis segitségét kérnék, leragadtam a VLSM számolásoknál :
    icnd1-nél jároik még. Van 1 feladat a könyben:

    Practice Adding New VLSM Subnets
    Your boss wants you to add one subnet to an existing design. The existing design already
    has these five subnets:
    10.0.0.0/24
    10.0.1.0/25
    10.0.2.0/26
    10.0.3.0/27
    10.0.6.0/28
    The boss cannot decide among five competing subnet masks to use for this next new subnet
    to add to the internetwork. However, the boss wants you to practice VLSM and plan the
    subnet ID that he would use for each of those four possible masks. He tells you that the
    new subnet ID must be part of Class A network 10.0.0.0, that the new subnet must not overlap
    with the original five subnets, and that the new subnet ID must be the numerically lowest
    possible subnet ID (without breaking the other rules). Pick the one subnet ID that you
    would plan to use based on each of the following mask choices by the boss:

    1. /24
    2. /23
    3. /22
    4. /25

    Van is megoldás a könyvben, de sehogy sem esik le, miért /24es subnet keresésnél a 3-ik oktet az interesting octet amikor 255.255.255.0 a prefixe?

    The subnets would be 10.0.0.0, 10.0.1.0, 10.0.2.0, 10.0.3.0, 10.0.4.0, 10.0.5.0,
    and so on, counting by 1 in the third octet.

    Vagy már késő van nemfog az agyam :R
