Ok, i saw a topic liek this, but it does not fit my problem, so here it is: Every IP i try to scan it says : "Note: Host seems down. If it is really up, but blocking our ping probes, try -P0 Nmap finished: 1 IP address (0 hosts up) scanned in 4.328 seconds" I'll copy it : (example with redrooster.com)

C:\hacks\Nmap>nmap redrooster.com

Nmap finished: 1 IP address (0 hosts up) scanned in 4.328 seconds

C:\hacks\Nmap>ping redrooster.com

Pinging redrooster.com [64.40.102.44] with 32 bytes of data:

Ping statistics for 64.40.102.44: Packets: Sent = 3, Received = 3, Lost = 0 (0% loss), Approximate round trip times in milli-seconds: Minimum = 210ms, Maximum = 221ms, Average = 214ms Control-C ^C Yeah, the most funny thing is nmap can`t scan it, but default ping is receiving reply's… :( The strange thing is, it works on neighbours(which are on same ISP like me) P.S. I am using Windows SP1 & nmap version=4.11 Ask whatever you wanna know, by the way it's my first time using this program

try using other commands besides "nmap site.com"

nmap -P0 -O -vv -sS site.com P0 is a 'p' and a 'zero', but -O is an 'o'.
