About ipaddress.you

By Daniel Last updated July 3, 2026

ipaddress.you is an independent, ad-free tool that shows you your public IP address (IPv4 and IPv6) with your location, ISP, and hostname, plus a set of free network tools. It is run by one developer, funded by nobody, and built on a simple rule: your IP address is displayed to you, never stored by us.

What this site is

The home page answers one question instantly: what is my IP address? Unlike most IP checkers, the answer is rendered on the server, so you see your IPv4 and IPv6 address, city, ISP, and ASN even with JavaScript disabled. No spinners, no "detecting" placeholders.

Around that core sit focused tools such as the IP lookup, the WebRTC leak test, the IP blacklist check, and the subnet calculator, plus plain-English guides that explain how IP addresses actually work, without fear-mongering or a VPN subscription pitch at the end.

Who runs it

The site is built and maintained by Daniel, an independent software developer. You can find him on GitHub and X. There is no company behind the site, no sales team, and no advertising partner. If something is wrong or unclear, the fastest way to fix it is to write him directly.

Where the data comes from

Everything shown on this site is derived from your request or from databases hosted on our own server:

  • Your IP address is read from the connection your browser opens, the same information every website you visit receives.
  • Geolocation, ISP, and ASN come from local copies of the GeoLite2 databases. Lookups run entirely on our server; your address is never sent to a geolocation API. This product includes GeoLite2 data created by MaxMind, available from maxmind.com.
  • Hostnames are resolved via standard reverse DNS (PTR) lookups.
  • Blacklist results come from live DNSBL queries against eight reputable public blocklists (Spamhaus, SpamCop, Barracuda, and others).
  • The WebRTC leak test runs entirely in your browser. The result is shown to you and not reported back to us.

Why your IP is never logged

An IP checker that keeps a log of everyone who used it would defeat its own purpose. This site's application code never writes your IP address to a database, log file, or analytics event: it is read from the request, rendered into your page, and discarded. Because geolocation uses local databases, no third-party service learns your address either. The privacy policy spells out exactly what is (and is not) processed.

Frequently Asked Questions

Who runs ipaddress.you?
ipaddress.you is built and run by Daniel, an independent developer. It is not owned by a VPN company, an advertising network, or a data broker, and there are no investors whose business model depends on your data.
How does ipaddress.you make money?
It currently does not. The site is a self-funded side project with no ads, no paid tiers, and no affiliate funnels. Server costs are low because everything (including geolocation) runs locally without paid third-party APIs.
How accurate is the location shown for my IP?
It is an estimate from the local MaxMind GeoLite2 database, usually right at the country level and often at the city level, but it can be off by many miles. That is a property of IP geolocation itself, not of this site. No IP lookup can see your street address.
Do you log or store the IP addresses you detect?
No. Your IP is read from the request, rendered into the page, and discarded. It is never written to a database, log file, or analytics event. The privacy policy describes this in detail.
Can I use the data or the API in my own project?
Yes. The free JSON API (documented at /api) requires no key and allows cross-origin requests. Geolocation data comes from the GeoLite2 database created by MaxMind, so downstream use must respect the GeoLite2 license.
