Yeah, ~65 thousand makes the most sense here.

Wait, are we sure about the ~500,000 option? Sounds off.

No way it's ~5 million, that's way too high!

I thought it was closer to ~1 million, but I could be wrong.

It's definitely ~65 thousand for a /16 network.

I remember discussing how Discovery scans a range, but I can't recall the exact numbers. I might lean towards option B, but I’m not sure.

I want to say it’s more than 65,000, but I’m not confident. Could it be around 500,000 like option D?

I'm not entirely sure, but I feel like we practiced a question like this, and it had something to do with how many hosts are in a subnet.

I think I remember that a /16 subnet has around 65,536 IP addresses, so maybe it's closer to option C?

~5 million sounds way too high for a /16 network. I'm going to go with option C, ~65 thousand, since that seems more reasonable.

I'm not sure about the exact number, but I know that a /16 network has 65,536 possible host IPs. So the answer is probably around that range.

Okay, let's see. 180.181.0.0/16 means the network range is 180.181.0.0 to 180.181.255.255. That's a lot of IPs to scan!

Hmm, this seems like a tricky one. I'll need to think through the IP network range and how many host IPs that would cover.

I see your point, but I still think A) ~5 million makes more sense given the size of the IP network.

65 thousand? That's way too low. I'm going with D, half a million sounds more accurate.
