I'm seeing some strange mac addresses on a network [protected by a m0n0, the only shred of
on-topicness in this question :) ]
Specifically, I see the following addresses on a single edge port of a managed switch:
I suspect someone has hooked up another switch to this port (or perhaps a wireless AP), but I've
never seen macs like these before and they aren't listed in any mac manufacturer cross reference I
can find. They also aren't any ethernet multicast addresses either. Now obviously they could be
spoofed, but they seem a little too nonrandom in the later bits to be spoofed. I can't directly
look at what's plugged in to the port because it is in a private dorm room or I'd just take a look.
I did shut the port off though :)
Any one seen this before or have any insight?
Thanks and apologies for the OT, but I figured this was as good a networking forum as anywhere else.
