I don't understand why this is happening, maybe you have some insight.

Hi,

first of all, thanks for the script! I ran into an issue with it and I was hoping you might have some insight in the matter:

I used it as a starting point for a script that checks if a specific mac address is online or not. I originally tested the script on my laptop wifi interface and everything worked like a charm. Then I moved the script to the intended device (an orange pi with wifi running an Ubuntu variant) and the very same script starting trying to ARP 169.254.0.0/16 instead of 192.168.1.0/24 as it was doing on the laptop. The laptop and the orange pi are obviously on the same network. I made an ugly hack checking the address against the network we're trying to ARP, but I feel I'm just not understanding some basic networking here. The output of ifconfig seem identical to me except for the last part of the IP so I'm not even sure what else I could check.

Here's the hack: ferdinandyb@e207220

Thanks,
Bence
