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
speculation. ARP is pretty lightweight anyway, so I wouldn't be too
concerned about it soaking up bandwidth.
