We’ve hidden a host on this network that is

I am currently taking the Penetration Testing and Ethical Hacking verification and have the Nmap Basics and have the problem that the server is not reachable (We’ve hidden a host on this network that is blocking discovery probes. This host is somewhere between 172.16.0.10 and 172.16.0.20. Can you find it?)

and i can’t answer the question like that and have been working on this question for an extremely long time…
and that’s why i would like to know what the answer is for the whole series because then of course the other questions can’t be answered in this series either

Discover hosts in that range 10 to 20. The instractions also say what methods you should use. If any problems just ask
