About Ideal scan learning

[Mozamme Hosen Faraizi]

i have used this command for learn ideal scan

nmap -sI 192.168.1.1 -T4 -v -Pn 172.16.1.2

192.168.1.1 = zombie IP ---------- right?

172.16.1.2 = destination IP ------------ right ?

why this message " Idle scan zombie 192.168.1.1 (192.168.1.1) port 80 cannot be used because it has not returned any of our probes -- perhaps it is down or firewalled.
QUITTING!" ?

why this message "Host discovery disabled (-Pn)." ?

 

please help me
