nmap ping scan (with fixed digit) produces unreliable results

[Peter Van Eeckhoutte <peter.ve () corelan be>]

Hello,

I was trying to find a way to make nmap ping hosts on my networks,
using a fixed digit

Let's say I want to ping all hosts ending in .3

I have tried

nmap -sP -v 192.168.0-255.3
nmap -sP -v 192.168.*.3

Both actions seem to trigger echo requests, but nmap returns that most (or all) of these hosts are up (which is not the 
case)

Could this be a bug ?

Cheers
