The part messing with my head is that they're variations of the Mikrotik MAC, and not the actual MAC of the interface.  When it had 94 IP's did it come up with 94 unique MAC addresses?

Really sounds like the hotspot package.

Maybe proxy arp.

    Ok, have a strange situation that has repeated itself
    and I can come up with no answer.  Customer behind
    an ePMP 1000, mikrotik HAP 52.  Suddenly last night
    the ePMP radio went from 1 LAN MAC (the tik) to 43
    (forthy-three) MACs, most of them a variation of the
    actual MAC of the TIK.  At this time the TIK started
    grabbing (using) a swath of different IP, all part of
    our network (both public and private) but some of
    them not part of our wireless network.
    (EG the 100, 101, 102.X nets are part of our wireless
    but the 118.x network is not)

    Suspend ethernet on radio, wait 5, unsuspend and
    login to TIK, reboot, reboot radio.  all normal again.
    (cannot get into tik without doing this).

    This happended to the same customer, on different
    private (radio) and public (tik) IP address in April 2020
    at which time the radio had 94 MAC address on the LAN
    interface.  At that time we installed a new ePMP and went
    from a 952 tik to the HAP 52 thinking one of them was the
    issue.

    Thoughts ?  Suggestions we can look at ?

    PS:  this customer is computer illerate and generally does
    exactly what the tech says to do and there is no other
    internet service at this location.
