Hrm...wouldn't that be a bug in arping program?
How can one get "-1" responses?
And I can't reproduce that here (ia64-linux):
gsyprf3:~# ifconfig ib0
ib0 Link encap:UNSPEC HWaddr 00-00-04-04-FE-80-00-00-00-00-00-00-00-00-00-00

There is no 10.0.0.55 IP in use on this network.
I don't understand if the above result is correct or not
and I did RTFM.
BTW, I'm using Debian "iputils-arping 20020927-2".
