hello @ruan_defesacibe
Are you talking about Meraki or MerakiGo? If it is Meraki, you need to post your question here: Meraki Community , this is the MerakiGo-forum.
If you're looking for the information on MerakiGo, do this:
Open the MerakiGo-App or sign in to web.meraki-go.com
Go to the Tap "Hardware" and select your device, scroll down and you will see Product Information. Public IP might be what you are looking for I guess.
cheers
