ping 100% loss; 'arp -a' blew up

HELLLPPPP!

I have been trying to setup my linux for access to my local ethernet.  I am
using an ne2000 ethernet card and have upgraded my hard-drive to Caviar 2700
with 16 heads and 1654 cyls. (810 mb).  I am running with 16mb ram and linux
kernel 1.1.92 (I had the same problem on 1.1.18).

When I try to ping another machine on my net (199.72.92.3), ping reports 100%
packet loss.  when I type arp -a I get ip addresses that do not exist on my
ethernet.  and the ethernet addresses are wrong.  I have included dmesg,
ifconfig, route, and arp -a:

Thanks!
