What do you mean by every IP has identical MAC ?
You mean that all the IPs you are seeing are sharing the same MAC ?
This can be seen if this is the MAC for your Gateway ...

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

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?
