Actually, Tsu was right and BCD are correct (just checked this), so you can consider this question fake.

A and E are bradcast addresses. BDC are correct.
You just need to change the addresses to binary and check it yourselfs.

Um, isn’t C also a broadcast address (since last octet is 255)?

172.16.255.255/14
assuming that we can use a /14 subnet in a B class (we shouldn’t):
/14=255.252.0.0 , the magic number is 4. We have
172.0.0.0 as first subnet ID
172.4.0.0 as first subnet ID
172.8.0.0 as first subnet ID
then we have a range of 172.4.0.1 to 172.7.255.254 and 172.7.255.255 is the broadcast address.
No, 172.16.255.255/14 isn’t a broadcast address, just the mask is wrong in a B class 🙂

Sorry: then we have a range of 172.16.0.1 to 172.19.255.254 and 172.19.255.255 is the broadcast address.

Sorry folks,
B/D are right.
C is wrong cause a class B should not have a subnet <16 bit.

B/D are right.

I agree with you Willyx.

So why not A and E? Both of those are broadcast addresses, while B and D are Hosts.
Hosts match a type,
Broadcasts match a type
Which is the correct match?

But WHY is B/D correct? That has NOT been explained. As I mentioned, A/E match in the context that they are both broadcasts as well.

B/D are correct, they are both valid IP address within their subnet
A: 10.230.33.15/28 is the broadcast address for the network with subnet mask 255.255.255.240
D: 172.25.44.96/26 is the Network ID based on the subnet mask 255.255.255.192
E: 192.168.73.223/29 is the broadcast address for the network with subnet mask 255.255.255.248

Let me expand on my last comment ..
B/D are correct, they are both are valid HOST IP addresses within their subnet, whereas A,D & E are either the subnet IP or broadcast IP addresses.
Hope they helps?
