[olug] nmap paranoia

[Dave Rowe]

Okay, so just to play around with nmap, I tried running it with the 
following command:

~$ nmap -v -sP 192.168.2.0/16

which, appears to have scanned the entire 192.168.* subnet (/16, not 
/24, whoops).  So, anyways, I started getting results back, like, 
192.168.6.2 appears to be up, etc.

Here's the thing, my local network is 192.168.2.*.  So, I tried going to 
192.168.6.2 in a browser, and I got an authentication popup (HTTP-Auth) 
for "Security", clicking 'Cancel' just says 'Error Loading!!!', some 
number, then what appears to be a timestamp.

Anyone seen something like this?  I'm on Cox, with no additional 
connections that I'm aware of (ie, no VPNs, etc).
