from the Fine Manual:
       -s hostname hw_addr, --set hostname
              Manually create an ARP address  mapping  entry  for
              host  hostname with hardware address set to hw_addr
              class, but for most classes one can assume that the
              usual  presentation  can be used.  For the Ethernet
              class, this is 6 bytes in hexadecimal, separated by
              colons.  When  adding  proxy  arp  entries (that is
              those with the publish flag set a  netmask  may  be
              specified  to proxy arp for entire subnets. This is
              not good practice, but is supported by  older  ker­
              nels  because it can be useful. If the temp flag is
              not supplied entries will be permanent stored  into
              the ARP cache.

I suspect that if it's a permanent entry it won't refresh, but that's 
mere
speculation. ARP is pretty lightweight anyway, so I wouldn't be too
concerned about it soaking up bandwidth.

Cheers,
Waider.
