Don is right, the manpage clearly states that the -n option sould supress symbolic name lookups, but no matter how hard I try I cannot elicit a DNS query out of ping. I run named on my local network. First, I pinged an IP address that I knew my system would not have cached anywhere - no DNS lookup. Then I disabled named and tried again with a few new IP addresses - still no DNS queries. Then I even went so far as to rename my hosts file. At this point I couldn't even ping 'localhost' by name. Each time, the ping worked fine and never once issued a DNS query - I was watching with ethereal. Is the manpage incorrect? Further, the OP's gateway machine should have no effect whatsoever on his ability to ping another machine directly connected to his switch. This problem is mighty strange.
