I noticed the same thing here, when I first got my hookup.  There was
a lot of mindspring and earthlink arp traffic.  I just did a quick dump
this morning (I dumped with -n to prevent dns traffic) and found around
1000 arp requests in 60 seconds.  A little grep, awk, and sort shows
that it is concentrated to only a few sources.

I also found (well, google found) that we are not the first ones to
notice and it is not specific to our geography.
