Along with that, ARP requests are only sent to the local network and not
"the world". They don't survive past a router since, as noted above, their
purpose is to obtain the MAC address equated to an IP address and MAC
addresses are only used on the local subnet.
A network configuration error could explain what you are seeing. However,
without additional information we can't help much.
