route command uses reverse dns lookups to display hostname/network
names. route -n does not. I suspect route -n works for you. route
probably does too if you wait enough minutes for dns to timeout.
pinging by hostname on the otherhand does normal dns lookups (name to
ip) not reverser (ip to name). To me this means you have a problem with
doing reverse dns lookups of some IPs, while forward lookup of domains
