Re: What does a network having all identical MAC addresses mean?

('binary' encoding is not supported, stored as-is) I would guess that the AP was acting as a proxy for all connections, and you aren't "allowed" to connect directly to other machines. Was the MAC the MAC of the wireless AP? If so, yeah, that's a sort of security measure.

<- snip ->
I was in a free wi-fi hotspot the other day and just for kicks ran an
NMAP scan to see how many people were logged on.

I noticed something peculiar though. Every IP address had identical MAC
addresses. Is this some security thing the hotspot had going on? Or is
it some kind of devious thing going on by one of the other customers in
the hotspot?
