Tips, get allocated device IP for mac OS X Internet share

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.
