I have found the same logs on one of my older builds (4.3 I think). The
offending MAC address was found to be a Cisco router on my ISP's network. I
found no solution for it though.

  Anyone have any ideas as to what might be causing the following to appear
in my security report?

   arp: 12.236.220.1 moved from 00:b0:64:b7:6f:54 to 00:b0:64:b7:6f:a8 on
dc0

  I thought those : delimited fields would be MAC addresses, but they don't
match the MAC addresses of either of the two cards in my free-bsd box.  I
have not checked the MAC addresses of the other network cards on my network.

  Also, where does the "server /kernel" name come from.  "kernel" is not the
name I gave my kernel, so I am suspicious.

  Thanks,

  --Craig
