Probably because your machine can't route to those addresses?

`ping 192.168.1.2` would likely give you the same result

As a random guess, I would suspect your netmask may not be what you expect it is.

with a different network config?

It works fine with the /24 that I'm on when I run nmap -sP XXX.XXX.XXX.\*

and if I copy you: 

% nmap -sP 192.168.1.\*

Starting Nmap 5.50 ( http://nmap.org ) at 2011-03-18 15:39 EDT
Nmap done: 256 IP addresses (0 hosts up) scanned in 103.04 seconds

(since my local network has a default route and I'm not using 192.168.1.0/24 internally)
