Scott is right. This becomes a basic layer 2 versus layer 3
networking question. It is absolutely worth learning the difference
if you want to feel more confident in your networking troubleshooting
In this case, if your test host's routing table doesn't have a route
that matches 126.96.36.199, it will forward it to the routing table's
default gateway. The only ARP entry in use at that point is that of
Traceroute, mtr, and hping are great tools to see where it actually
does live out there on the network.
