Short story, I’m updating a Laird gateway connected to my mac book and using the Wifi connection to reach Internet. I need to get the allocated IP to access it using the web UI.
I found two ways (only one working) on Internet:
[~] ping 192.168.2.255
This way, you can get different devices responding to the ping broadcast and list the addresses. I’ve got nothing interesting but it’s good to know.
[~] arp -i bridge100 -a ? (192.168.2.5) at (incomplete) on bridge100 ifscope [bridge] ? (192.168.2.9) at xx:xx:xx:xx:44:dd on bridge100 ifscope [bridge] ? (192.168.2.99) at (incomplete) on bridge100 ifscope [bridge]
Here we have a device responding on 192.168.2.9 where the Laird is.
