I agree with Royce, the correct answer is A) 256 because each octet covers 256 addresses.

But if we consider the IP range, it covers 256 addresses for each octet, so it should be A) 256.

C) 1024 is the way to go! Might as well do a full sweep of the network while we're at it. What's the worst that could happen?

D) 64 seems too low, and A) 256 is too simple. I'm going with B) 512 - gotta cover all those IP addresses!

I think the answer is C) 1024. That's a lot of hosts to scan, but nmap is pretty fast, right?

That's good to know. I'll go ahead and run the command to scan all 1024 hosts.
