Instantly see your public IP address plus your browser, user-agent, device, screen, timezone and connection details. Free and runs in your browser.

Your IP is fetched in your browser from a public lookup endpoint; everything else is read from your browser. We never log or store any of it.

About What Is My IP

What Is My IP shows your public IP address the moment the page loads — the address websites actually see when your device connects — labeled as IPv4 or IPv6, together with an approximate location estimated from the address. Below it, the page assembles everything your own browser reports about itself: browser and engine, user agent, operating system, CPU cores, device memory, touch points, languages, time zone, local time, screen, viewport, pixel ratio, color depth, connection type, online status, cookie support and Do Not Track.

The device details are read locally by your browser and never leave your machine, and your IP details are not logged or stored. The location shown is an estimate derived from the IP address — it points at your provider’s registration area, not your exact position.

A separate lookup box lets you research any public IPv4 or IPv6 address: enter one and the tool returns its registered city, region, country, time zone, coordinates, postal code and reverse-DNS hostname (PTR). Lookups are answered by this site’s own endpoint, cached for a few minutes and rate-limited; private and reserved addresses are refused.

How to use What Is My IP

  1. Open the page — your public IP appears at the top with an IPv4 or IPv6 badge.
  2. Use the Copy IP button to grab the address for a support ticket or firewall rule.
  3. Scroll through the browser, system, display, locale and network sections to review what your browser exposes.
  4. To research another address, type any public IPv4 or IPv6 address into the lookup box and press Look up.
  5. Read the returned city, region, country, time zone, coordinates and PTR hostname.

Frequently asked questions

It is an estimate based on where your address is registered, usually correct at the country or city level but never precise to a street. VPNs, mobile carriers and corporate networks can shift it considerably. It is not GPS.

Your network reached this site over IPv6, so that is the public address the server saw. Many providers now prefer IPv6 when both protocols are available; your device typically still holds an IPv4 address as well.

You can look up any public IPv4 or IPv6 address and see its registered city, region, country, time zone, coordinates and reverse-DNS hostname. Private and reserved ranges such as 192.168.x.x are refused because they have no public registration.

It is the reverse-DNS name registered for the address — often revealing the ISP or hosting company behind it. Not every address has one; when the owner has not published a PTR record, the field stays empty.

No. Your device details are read locally by your browser, and your IP details are not logged or stored. Lookups of other addresses are cached briefly so repeated queries stay fast, and requests are rate-limited.

Yes. Seeing your own IP, browsing your device details and looking up other public addresses are all free, with no account needed.
