    For subnet B I got:

    18 bits in the subnet mask

    subnet mask 255.255.192.0

    4 total subnets

    4094 hosts.

    Now I'll just list the subnets:

    192.168.0.1-192.168.63.254 (can't use first or last addresses 192.168.0.0 and ..63.255)
    192.168.64.1-192.168.127.255
    192.168.128.1-192.168.191.255
    192.168.192.1-192.168.255.255

    I'll leave the next one to you.

    I promised I wouldn't plug my own videos, but I'm going to because this video covers pretty much everything you're asking, so hopefully it helps you:

    SUBNET B

    SPECIFICATION INPUT


    Number of bits in the subnet: 18

    IP mask (binary): 11111111.11111111.11000000.00000000

    Maximum number of usable
    subnets
    (including the 0th subnet) 4

    Number of usable
    hosts per subnet 16382( that is, 16384 - 2 for network and broadcast address)

    IP Subnet 192.168.64.0

    First IP host address 192.168.64.1

    Last IP host address 192.168.127.254

    Is that correct, anyone?

    This feels oddly like you're asking help with a homework worksheet, lol. But I could use those questions for myself for practice, since my subnetting is a little rusty :)
