bind and arp

[Joseph Fannin]

    I upgraded to bind 9.1.3 from 9.1.0 today, and now I'm seeing a
problem similar to the one Piet Pelz is describing in the thread
'named is causing severe traffic'.  For some reason, the named on my
gateway machine is doing a reverse lookup for every arp
broadcast it recieves from the entire cable modem network it's
connected to.  None of these requests are even for my own IP; they
usually originate from one of my ISP's machines are are inquiring
about other addresses on the ISP's network:

04:34:43.366891 arp who-has dhcp065-024-127-146.columbus.rr.com tell dhcp065-024-124-001.columbus.rr.com
04:34:43.426883 dhcp065-024-121-117.columbus.rr.com.1041 > clmboh1-dns3.columbus.rr.com.domain:  58012+ PTR? 146.127.24.65.in-addr.arpa. (44) (DF)
04:34:43.436881 clmboh1-dns3.columbus.rr.com.domain > dhcp065-024-121-117.columbus.rr.com.1041:  58012* 1/2/2 (179) (DF)
04:34:45.016662 arp who-has dhcp065-024-123-204.columbus.rr.com tell dhcp065-024-120-001.columbus.rr.com
04:34:45.056657 dhcp065-024-121-117.columbus.rr.com.1041 > clmboh1-dns3.columbus.rr.com.domain:  29006+ PTR? 204.123.24.65.in-addr.arpa. (44) (DF)
04:34:45.066655 clmboh1-dns3.columbus.rr.com.domain > dhcp065-024-121-117.columbus.rr.com.1041:  29006* 1/2/2 (179) (DF)

    Could this be a glitch in my configuration somehow?  I haven't read
anything involving configuring bind and arp.
