I'm supposed to be pinging 224, but it shows it pinging 183 which is
unreachable, yet then reports stats for 224.

Not quite, your PC is 183, so 183 is saying 224 is unreachable

I'm a networking tyro but - unlike some other posters - that seems to me
neither wholly surprising nor a failure as such nor something to which
Unix and Linux are immune. Search for "ping gives result for a
different ip address" and you'll find examples of what can cause it.

Just don't ask me to resolve it :)

No other OS I know of interprets an ICMP error response as a successful ping response :)

do you have a split subnet?
in linux i would want to see your client subnet configuration and
default route with 'ifconfig -a' and 'route'. I cant remember the
windoze commands.


it LOOKS like your default route is 10.131.97.183, and you are subnetted
to some other /25 or so subnet

While it does seem an odd way of doing it, there might be some sort of
sense to it. Having got a response back that the destination host was
unreachable does mean that the packets were not lost, just that they
could not be passed on, unlike if there were just no response and each
attempt timed out.

Fair enough if I have been wrong in interrupting that as (to paraphrase)
no more than "I counted 4 packets out and I counted 4 replies, so none
were lost" - ie nothing about which if any address was reached.

It's a perfectly normal windows message,

..183 is the machine doing the pinging of the .224 machine, the 183
machine is reporting that the 224 machine is not reachable, it's
different from "no reply".

tracert won't help much as both addrs are on the same subnet (assuming
typical /24 masks) and if you can't ping by numeric addr, then DNS
doesn't enter into it.

It's .224 which is unreachable, and it is .183 which is telling you so. The
'unreachable' messages wouldn't be counted as replies (just as error messages)
by any sensible operating system and the summary should stay 100% loss.

Unfortunately it might be as simple as the local connection saying 'I am
