About iptool
// what this tool is and why it exists
What is iptool?
iptool is a free, no-sign-up network diagnostic utility built by 1337co.de. Its primary purpose is simple: show you exactly what the internet sees when you connect to it.
In a single page load, iptool tells you your public IPv4 address, your public IPv6 address (if your network supports it), an approximate geographic location based on your IP, and a snapshot of your browser and device settings as seen by web servers.
Who is it for?
- Developers and network engineers — quickly verify which IP a machine is egressing from, confirm IPv6 connectivity, or inspect what your user agent string looks like to a remote server.
- Privacy-conscious users — understand what information your IP address reveals about your approximate location and ISP.
- VPN and proxy users — confirm that your traffic is routing through your VPN or proxy as expected, and verify whether your real IP is masked.
- Anyone curious — most people have no idea what their public IP address is or what it can reveal. iptool makes that information instantly accessible.
What does it show?
- Public IP (IPv4 & IPv6) — your network's externally visible address, detected by making dual-stack requests to separate endpoints that force each protocol independently.
- Geolocation — country, region, city, postal code, timezone, and coordinates estimated from your IP. This is approximate and can be significantly off, especially on mobile networks, VPNs, or satellite connections.
- Browser & device info — user agent string, language preferences, screen resolution, timezone, color scheme preference, and more — all read client-side by your browser without any server involvement.
- JSON debug payload — a copyable snapshot of all the above, useful for pasting into bug reports or support tickets.
Privacy
iptool does not store, log, or sell any of the information it displays. The tool reflects your own data back to you. See the Privacy Policy for full details.
