  • Confusion in VLSM subnetting

    Posted by Bertran Hammad on February 13, 2024 at 8:18 am

    This is the pdf I am studying from. This is not exactly what I need for my exams but it’s pretty clearly written and concept giving thing.

    192.168.10.0/24 is given IP address to subnet.
    We need 4 subnets
    So
    192.168.10.00 00 0000
    This is an ip address that has 3 octets of network address and 1 octet of host address. So a class C address.
    For 4 subnets, i need 2 bits of host to be borrowed.
    00 00 0000
    01
    10
    11

    So I get these IP address for subnets-:
    Subnet #0->192.168.10.0/26
    Subnet #1->192.168.10.64/26
    Subnet #2->192.168.10.128/26
    Subnet #3->192.168.10.192/26

    A) Take subnet #0. Perth 60 hosts

    The start address here is 192.168.10.0/26
    192.168.10.00 000000

    192.168.10.00 1111111

    This gives

    Network address=192.168.10.0 /26

    Broadcast address=192.168.10.63 /26

    B) Take subnet #1-:

    Kuala Lampur 28 hosts.

    Next subnet IP address was 192.168.10.64/26

    Question-: Why was this the next subnet IP address?

    Is it becuase of this?

    So I get these IP address for subnets-:

    “Subnet #0->192.168.10.0/26
    Subnet #1->192.168.10.64/26
    Subnet #2->192.168.10.128/26
    Subnet #3->192.168.10.192/26”

    Is it because the next consecutive ip address after the perth’s broadcast address is 192.168.10.64 /26?

    28 hosts required ie 5 host bits. I.e 27 network bits.
    192.168.10.010 00000
    192.168.10.010 11111
