Tale of two IP addresses ...

The same IP address does not travel with the phone, they are leased from your home router or a public router or whatever you are connected to at that time. While the routers IP "pool" may give you a similar IP address or the same internal IP address by chance (10,.. or 192,.. are common internal IP designations) your router itself has to have a uniqe IP address not used anywhere else on the internet - this can vary from network to network but no two devices can have the same external IP address. Internal IP's don't matter, there are possibly billions of networked devices with the same IP address that the router manages, because the internal IP's never need to go out to the internet.

Here's an example: You are home in Austin, your phone has the IP address from your router is 192.168.1.2, and that's what you see, but your routers IP address happens to be something like 24.148.77.6 you drive over to the Stevie Ray Vaughn memorial and you have a straight shot to the Wi-Fi at Hooters across the park, your IP address is (by fairly remote chance) 192.168.1.2, however Hooters's ISP is allowing the router to connect using 185.66.14.220 - these are all made up numbers, I don't know what the IP address is for Hooters ISP but I suddenly want Chicken Wings.

your internal IP (192.168.1.2) goes to the router, but no further. Your home router (with the made up address 24.148.77.6) takes the request from 192.168.1.2 and goes out over that 24.xxx.xxx.xxx IP address, comes back with the information you wanted (e.g. discussions.apple.com) and routes it back to 192.168.1.2 - your phone. The router is like a waiter, it takes your order and sends it to the kitchen (for chicken wings) then brings it to the the table, or your phone. So what google may be reporting is that IP address that was expediting these requests to use the internet from your device with the local IP address.

hope you get it sorted. 🙂
