I keep getting a message on my NetBSD machine.  My machine is called
pimpbot and is running the i386 version of NetBSD 1.2.  Here is the example
of the message that I keep getting

	Oct 30 21:29:53 pimpbot /netbsd: arp info overwritten for 80c10414 by
00:00:0c:06:c5:f9

The ethernet address sometimes is different, but I figured that didn't
really matter.  My question is what does this message exactly mean?  I know
it has something to do with the network, and probally someone is
overwriting my ip address, but I do not know what exactly this message
means.  Thanks for any help.
