My case: arplookup 0.0.0.0 failed: host is not on local network
I got strange messages in log: kernel: arplookup 0.0.0.0 failed: host is not on local network.
When I tried to resolve it for the first time different people in different blogs wrote that it’ok – don’t mind about it.
Someone adviced turning off the arp logging but I didn’t want.
I decided to inspect this issue closer.
After several hours parsing logs, tcpdump, and etc I found it. (tcpdump -v arp).
It was an ip-phone with default settings for DNS: 0.0.0.0.
I changed it to my DNS-server and the message disappeared.
