      Just to clarify:

      When I captured one of these packets, I noticed that the
    source MAC address was the same as the address in my ARP cache
    for an internal server. That was what I wrote in my initial
    description.
      Later, I realized that there's an (internal) router between
    me and that server, and so of course that MAC address is that of
    the router.
      So when I wrote my initial note, I thought I was seeing evidence
    that the packet had originated within my organization's network.
    By the time I wrote my follow-up message, I'd realized that all I
    knew was that it probably came from somewhere outside my SUBnet.
     
      Despite the initial error described above, I really DO
    know how my routers work. Please stop sending me explanations
    of how they work -- especially *incorrect* explanations. That
    wasn't my question.

      And to reiterate:

      Several people have suggested I check

    http://people.ists.dartmouth.edu/~gbakos/bindsweep/

    I have, and it appears to describe exactly what I'm seeing.
    Thank you.
