Your public address as the internet sees it — provider, network, and approximate location on the map — plus the private address your router gave this device, and exactly what our own server receives when you connect. Everything is fetched live and nothing is stored.
Your provider assigns one public IP to your router — that's the address every website, game server and speed test sees, shared by everything in your home. Inside the house, the router runs its own tiny post office and hands each device a private IP (usually 192.168.x.x): meaningful only on your network, invisible to the internet, and the reason two homes can both have a 192.168.1.20 without conflict. When the two public addresses above differ — the one from Cloudflare and the one our server sees — a VPN or proxy is usually sitting in between.
The public IP is your router's address on the internet, shared by all your devices. The private IP exists only inside your network; the router translates between them. Websites see the public one only.
City-level at best — it's where your provider registers the address block, often the nearest big city. It never reveals your street address.
No. Details render in your browser; the server endpoint only echoes what your connection already sent, and nothing is written anywhere.
