What these values mean

Your public IP is the address the internet sees — assigned by your ISP to your router — as opposed to the private RFC 1918 address (10.x, 172.16–31.x, 192.168.x) your device uses behind NAT. You may have both an IPv4 and an IPv6 address; many networks are now dual-stack and will prefer IPv6 when both work.

  • ASN / ISP — the Autonomous System number and organization that owns the address block and routes your traffic.
  • Reverse DNS (PTR) — the hostname the IP maps back to, if its owner published one.
  • Geolocation — an approximate, database-derived location. It is not GPS and is frequently wrong by city or even country, especially on mobile carriers or a VPN.

This lookup runs first-party on our own Cloudflare Worker — your IP is not handed to a third-party “what-is-my-IP” service, and nothing is stored.
