I thought all of these could be valid! What’s going on?

Nope, 80.33.5.7 is the only valid one here!

Wait, isn't 172 a Class B address?

Definitely B or D, but I think D is the right one!

Class B IPs range from 128.0.0.0 to 191.255.255.255.

I recall a question similar to this where option D was correct, but I’m hesitant because I might be mixing it up with class A.

I’m a bit confused about the ranges. I thought class B was 128-191, but I’m not confident about the specifics.

I remember practicing with IP address classes, and I feel like option B could be valid too, since it’s in the range.

I think class B networks start from 128 to 191, so I’m leaning towards option D, but I’m not completely sure.

This is a good test of my IP addressing knowledge. I'll methodically go through each option and check if the second octet falls within the class B range. I'm feeling pretty confident I can nail this one.

I'm a little confused by this question. I know IP addresses are divided into classes, but I'm not sure how to quickly identify a valid class B address. Maybe I should review my notes on IP addressing before moving on.

Okay, let me think this through. The class B network range is in the second octet, so I need to look for an address with 128-191 in the second octet. I think option B, 80.33.5.7, is the correct answer.

Hmm, I'm a bit unsure about this one. I know class B networks have a prefix of 10 in the first two octets, but I'm not totally confident in my ability to identify a valid IP address for that class.

This looks like a straightforward IP address question. I'll start by checking the class B network range, which is 128.0.0.0 to 191.255.255.255. Then I'll compare the given options to that range.

I'm a bit confused by the wording of the question. Is "continuum" the same as "continuous"? I want to make sure I fully understand the concepts before selecting an answer.

I'm just glad they didn't ask about the subnet mask. That's the real challenge in these networking exams!

Whoa, they're really trying to trick us with those other options! A) 225.128.98.7 is clearly a Class D multicast address, and C) 212.136.45.8 is in the Class C range. Good thing I remembered my IP address classes.

A) 225.128.98.7 is definitely not a valid Class B address, it's a Class D multicast address.

B) 80.33.5.7 is definitely the correct answer. Class B networks use the range 128.0.0.0 to 191.255.255.255, and 80.33.5.7 falls within that range.
