I'm supposed to be pinging 224, but it shows it pinging 183 which is

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.


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

Hint: We're laughing at the summary line, not the host unreachable.


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.
