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
