Does anyone know why these results would be different?


I'm guessing but I presume it is because unprivileged ping scan uses
connect(), so it has to establish a full connection to determine if a
host is up. Root ping scan uses raw packets and nmap assumes a host it
up if it gets any reply to its probe.

To be sure, run it with --packet-trace and you can see what is happening.
