Google has had the ability to look up your IP address for years now, just go to Google and search for [what is my ip] and Google will typically return your public IP address. What I didn't know is that this feature only works for those who have English language settings turned on. Region and location supposedly does not matter, it is about language.
In addition, it works with the new IP addresses the IPv6 addresses.
Peter Nikolow has one and shared this screen shot on Twitter:
Are you able to trigger this? Let us know when you cannot and what, if anything, funny you see.
