Proxy ARP allows a non-routing device to determine the MAC address of

a host on another subnet or network.

End stations that require Proxy ARP must view the entire network as a

single network. These nodes must therefore use a smaller subnet mask

than that used by the router or other relevant network devices.

Extensive use of Proxy ARP can degrade router performance because it

may lead to increased ARP traffic and increased search time for larger

ARP address tables.
