the prefix length is wrong, but in other cases i am at a loss - the hosts in the probed network actually seems to return more than one response per request. I have no idea why. We saw this with the 193.55.112.0/24 network, for instance (which has now been fixed).
this could be because a) there could be a 10.0 internal LAN remapped into a normal IP space? b) on some versions of unix, when you open /dev/icmp, you will receive ALL ICMP activity received by the machine, so if your application doesn't look too closely at the pongs (response to a ping :-), it might see response to other pings occurring Paul ---- P Mansfield, Senior SysAdmin PSINet, +44-1223-577577x2611/577611 fax:577600 :r~/humour/signature :wq
