    if you have an IP subnet do you consider the first IP (aka the network ID) as apart of that subnet or not?

    ex.

    is 172.16.10.16/28 in the same subnet as 172.16.10.22/28

    if you think the ID is apart of its own subnet then you would answer yes, however if you think the ID is not apart of it's own subnet then you would answer no.

    but i need some opinions on this, it's a hot topic in my work center right now, and so far im on my own.

    172.16.10.16/28 equals

    Subnet: 172.16.10.16
    Mask: 255.255.255.240
    Subnet size: 14
    Host range: 172.16.10.17 to 172.16.10.30
    Broadcast: 172.16.10.31

    So the answer is YES
