I've posted the same question to netbsd-users recently. Start "tcpdump 
-i your_external_if -n arp" and you will see crazy ARP queries like 
this:

17:31:45.776665 arp who-has 192.168.7.81 tell 62.85.88.1
17:31:45.779798 arp who-has 192.168.7.62 tell 62.85.88.1
17:31:45.780804 arp who-has 159.148.92.163 tell 62.85.88.1
17:31:46.855691 arp who-has 192.168.7.104 tell 62.85.88.1
17:31:46.858823 arp who-has 192.168.7.60 tell 62.85.88.1
17:31:46.862458 arp who-has 159.148.92.170 tell 62.85.88.1
17:31:47.914021 arp who-has 192.168.7.227 tell 62.85.88.1

At least two ISPs (at home and at work) use packets like this for 
something security-related. This drives both FreeBSD and NetBSD crazy. 
I believe there should be sysctl for nearly meaningless network 
warnings like this.
