Pinging failing addresses randomly returns working in windows

Steps:

• Connect to wireless network.
• Start cnping {Address}
• Disconnect from wireless network.

Wait.

Can confirm on my Windows 10 VM. Even without changing network settings I get a few responses at the very beginning and every now and then. Weird, I'll see what I can do!

[dreua]

It's a very regular pattern in my case...
Also tried 192.168.15.233 same result.

Interesting: Different pattern for 192.168.122.233 which is a IP on the local network but there should be no host assigned to it:

Downloading wireshark...

Looks like it is possibly showing a 'reply from x.x.x.x destination host unreachable' as a valid ping.

[dreua]

Yeah that could be the case. I was thinking in that direction, too. Will have a look with wireshark soon...

Wireshark confirms @dark-spark s idea. "Destination network unreachable" ICMP responses show up whenever cnping shows ping returns. @dark-spark Would you like to fix this or should I have a look?

[dark-spark]

@dreua Could you please have a look?

One line change but it took me some time to find it 😉
