Hmm. I think that depends on how you have your PC configured. I've
configured them one of two ways:
1. with the default gateway pointing to a router address. The PC should
just be arping for devices on the local subnet. Since a default gateway is
present, the PC should (_should_) send packets destined for different
subnets directly to the default gateway (without an arp - possibly one to
get the MAC address of the router). proxy-arp on or off for this scenario
should not make a difference.
2. have the PC be its own default gateway. In this case, the PC will arp
for just about everything. As long as the router is configured for
proxy-arp (on by default on Cisco routers), there should not be a problem.
I think you're talking about a third situation where there is no default
gateway configured at all. I would expect the device to say network
unreachable since it doesn't know how to get anywhere.

I have tested the proxy arp with Windows95/98 PC.
When it does not know about the destination, it DOES NOT arp for it, it
will
just display a message : network unreachable
I think a unix machine will try to ARP for the unknown network.
