Try getting a full packet capture of the following commands.

sudo arp -d 192.168.1.1
sudo nmap -sP --send-ip 192.168.1.1

Here's the output.  It looks OK to me, unless I'm missing something?

That looks right, but what I want is a pcap/tcpdump traffic capture like
you sent before. What I'm looking for is the ARP packets sent by the
operating system.

Is this on Snow Leopard?
