IP Address Lookup

Geolocation, ISP and details for any IP

This tool makes a real outbound request. The address you type travels to ipwho.is as part of the lookup URL, and the reply comes back to your browser; this site stores neither. The map and detail buttons contact openstreetmap.org and ipinfo.io in a new tab, but only when you press them.

What is IP Address Lookup?

Type any IPv4 or IPv6 address and the page asks ipwho.is about that address rather than about yours, then lays out the answer: continent, country, region, city, postal code, coordinates, the IANA timezone with its current local time, and the carrier with its autonomous system number. Four preset buttons — 8.8.8.8, 1.1.1.1, 9.9.9.9 and 185.199.108.153 — show what a public resolver, two DNS providers and a GitHub Pages host report without any typing. Once coordinates come back, a button opens OpenStreetMap centred on them and a second opens the same address on ipinfo.io, which is a fast way to compare a second data source. A copy button grabs a one-line summary of address, location and carrier.

Look up any IPv4 or IPv6 address and see its country, city, region, timezone, ISP and organization. The lookup runs from your browser against a free public API — no signup required.

Step-by-Step

How to use IP Address Lookup

1

Type the address into the IP address field — the placeholder shows both a dotted-quad IPv4 and a colon-separated IPv6 form — and press Lookup.

2

Or press one of the four preset buttons to query 8.8.8.8, 1.1.1.1, 9.9.9.9 or 185.199.108.153 straight away.

3

Read the Results panel: ISP, Organization, ASN, Continent, Country, Region, City, Postal code, Timezone, Local time and Coordinates.

4

Press View on OpenStreetMap to centre a map on the coordinates, or More details to open the same address on ipinfo.io.

Key Capabilities
  • Accepts both address families; the placeholder demonstrates the dotted-quad IPv4 form and the colon-separated IPv6 form.
  • The address you type is sent as a path segment to https://ipwho.is/, and nothing about your own connection is attached to it.
  • Carrier name and autonomous system number sit next to each other, which identifies the network operator more reliably than the name alone.
  • Two independent cross-checks are one click away: a map centred on the returned coordinates, or a second geolocation database.
Common Use Cases
  • A support engineer reads back the autonomous system number for an address in a log file to establish which network operator owns it.
  • A developer checks whether a host in their configuration sits in a public cloud range before trusting its allowlist entry.
  • A site owner investigates unfamiliar access-log entries by pasting several addresses and comparing carrier and country.

Frequently Asked Questions

How accurate is the city it returns?
Country and region data is usually correct. City is inferred from the block an operator registered with its regional registry, so a mobile subscriber can appear hundreds of kilometres away, and a VPN exit carries the operator's city rather than the user's.
Can I look up an address that is not mine?
Yes, and that is the main use. Any routable public address can be queried, including ranges you have never visited. Private addresses such as 192.168.x.x or 10.x.x.x exist only inside a network and have no public location to return.
Why do some IPv6 addresses come back empty?
IPv6 is commonly allocated as a single host address out of a very large provider block, and geolocation databases trail new allocations. A miss is more frequent for IPv6 than for IPv4 and says nothing about whether the address is reachable.
Does looking an address up reveal who is asking?
It does not. The request carries only the address in the URL path, there is no account, no search history kept here and no analytics on this panel. That address is of course visible to ipwho.is as part of serving the lookup, exactly as it would be for any resolver.
