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.
