Only true if you're pinging the broadcast address of a network that you
have an interface on, or the system has other knowledge of the netmask/etc.
If you're pinging a remote addre
At least I think that's how it works. :)

She'd have to actually specify -b to ping a broadcast address, and if
she did, she would only get replies back from the hosts on that
subnet, not duplicate replies from the same IP.

What's your netmask? Is 192.168.0.95 your net's broadcast address?

Check your ARP tables, local and on intervening switches/routers. Make sure
there are no duplicate entries for that IP. If you note the response time, the
second packet is always higher which might be indicative. I would also check
for a botched MITM a la C&A.
Even if there is no obvious AR

Are the source and target on the same subnet? Have you checked the
source MAC address of the response?
