This is a cool Google feature. If you type in “Check My IP” into Google, Google will return your device’s current public IP address. (I tested this on my laptop connected to wifi and my iPhone connected to AT&T.)
This is a great tip for those occasions when you need to troubleshoot a network connectivity issue.
PS - Yes, I edited the IP Address in the screenshot, as you all know, an IPv4 IP Address should have four octets like xxx.xxx.xxx.xxx ranging between 0.0.0.0 to 255.255.255.255
