IP Checker
Through your own proxy, phone or profile, this page lets you see exactly what a website sees: the address, which of AT&T, T-Mobile or Verizon it belongs to, if any, the metro it resolves to, and whether your browser time zone or WebRTC disagrees.

How to read it
A Dedicated Mobile Proxies line shows the ISP as a US mobile carrier, because its address belongs to the carrier's pool and many real phones share it through carrier-grade NAT. The location will show the metro or state, not a street. Keep an eye on the two giveaways for an account, a browser time zone out of step with the IP and a WebRTC candidate that reveals your home or office address. Once those are fixed in the browser profile, check again.
