IP Address Lookup

Look up any IPv4 or IPv6 address to see the country, region, city, approximate coordinates, time zone, and the network it belongs to, including the ASN and organization name. Check one address, or paste up to 100 at once and export the complete results as CSV or JSON. Leave the box empty and it shows your own public IP. It is free and needs no sign-up.

  • Resolves country, region, city, coordinates, time zone, ASN, and network operator for one IP
  • Batch mode looks up as many as 100 addresses in a single request
  • Shows your own public IP the moment the page loads
  • Handles IPv4 and IPv6, and labels private, loopback, and reserved ranges without a network call
  • Exports batch results to CSV or JSON, and copies any result with one click
Enter an IPv4 or IPv6 address and press Look up. Its country, city, coordinates, time zone, and network operator will appear here.

Overview

One page that answers where an address is, which network runs it, and whether it is even a public address at all.

  1. 01

    Full geolocation for one IP

    Country, region, city, postal code, approximate latitude and longitude, an accuracy radius, and the local time zone, all in a single card.

  2. 02

    Network and operator (ASN)

    The autonomous system number and the organization behind the address, so you know whether it is a hosting provider, an ISP, or a corporate network.

  3. 03

    Batch up to 100 at once

    Paste a whole list, and every valid address comes back in one table you can scan, sort visually, and export.

  4. 04

    What is my IP

    Leave the field empty, or open the page, and it shows the public IP your connection is currently using, with its full location.

  5. 05

    IPv4 and IPv6

    Both families are recognized. IPv6 addresses are normalized before comparison, so compressed, expanded, and case-only forms of the same address do not slip through as duplicates.

  6. 06

    Private ranges labeled locally

    Addresses like 192.168.0.1 or ::1 are classified in the browser and marked private or reserved, with no wasted request to the server.

How to use

Single lookups answer on their own as the page loads; batch lookups take a pasted list and return a table.

  1. 01

    Open the page to see your own public IP, or type any IPv4 or IPv6 address into the box.

  2. 02

    Press Look up, or pick one of the example addresses, to see the full location and network card.

  3. 03

    Switch to Batch lookup, then paste up to 100 addresses separated by new lines, commas, or spaces.

  4. 04

    Read the valid, duplicate, and invalid counts, then press Look up to fetch the whole list at once.

  5. 05

    Copy a single result, or export the batch table as CSV or JSON for a spreadsheet or a script.

Details

An IP is a starting point for a lot of different questions, so the tool keeps location, network, and address type on one screen.

  • Country and city geolocation put an address on the map for abuse reports, analytics, and support tickets
  • The ASN and organization help indicate whether traffic may come from a data center, a home ISP, or a mobile carrier
  • Batch mode turns a log-file column of addresses into a single sortable, exportable table
  • Anycast, anonymous-proxy, and satellite flags add context, but none alone proves a VPN, CDN, or traffic type
  • Private and reserved ranges are labeled instead of being sent off for a pointless lookup
  • Every result copies as plain text, and batch results export straight to CSV or JSON

Use cases

Whenever an IP address turns up in a log, a form submission, or an email header, a quick lookup usually answers the next question.

  1. Investigate suspicious traffic

    Check whether a request came from a hosting provider or an unexpected country before you block it or open a ticket.

  2. Enrich server logs in bulk

    Paste a column of client IPs from an access log and get country, ASN, and operator for the whole set at once.

  3. Find your own public IP

    Confirm the address your network shows to the world, and whether a VPN or proxy is actually changing it.

  4. Inspect a mail relay

    Read the trusted Received chain first, then check a relay IP for its approximate country and network; it does not prove the original sender.

  5. Review a hosting or CDN provider

    Match an address to its ASN and organization to confirm which provider or edge network is serving it.

  6. Sanity-check analytics or fraud rules

    Spot data-center and proxy addresses that skew traffic numbers or trip up geolocation-based rules.

If you only need to convert an address between notations or classify it offline, the IP Address Converter does that in the browser without a lookup. To work out the range and mask of a whole network, open the Subnet Calculator. To check the service, risk, and exposure guidance for a port used by that host, see the Port Reference.

Best practices

IP geolocation is an estimate, not a fact on the ground, so treat the result as a strong hint and confirm anything that matters.

  • Read the accuracy radius before trusting a city: a large radius means the point is a regional guess, not a street.
  • Country and ASN are often more stable clues than an exact city, but neither is proof of a person, device, or intent.
  • Expect VPN, proxy, and mobile-carrier addresses to resolve to the provider, not the person behind them.
  • De-duplicate a log column first; the tool already drops repeats, which keeps you well under the 100-address limit.
  • Export to CSV or JSON when you need a record, rather than re-running the same lookups by hand.
  • Cross-check a decisive result against a second source before you act on it.

Limitations

This tool reports what a geolocation database knows about an address. It does not track people or watch live connections.

  • Geolocation is approximate. City-level results can be tens of kilometers off, and some addresses resolve only to a country.
  • An IP address does not reveal a name, a household, or a street address, and it should not be treated as identity.
  • Private, loopback, and reserved ranges have no public location, so they are labeled locally with no result to show.
  • A public address with no record in the database returns a clear "no location" message rather than a guess.
  • Opening the page asks the DevKitLab lookup service to identify your public IP. Addresses entered manually or in a batch are sent to that service for lookup.
  • The batch endpoint takes at most 100 addresses per request; larger lists are trimmed to the first 100.

FAQ

Common questions about accuracy, batch limits, privacy, and how the lookup works.

How accurate is IP geolocation?

Country is usually correct, and region is often right, but city is only an estimate and can be tens of kilometers off. Always read the accuracy radius, which tells you how wide the guess really is.

What is my IP address?

Open this page and it shows your current public IP right away, along with the country, city, time zone, and network it maps to. You can also click "Show my IP" at any time.

Can I look up many IP addresses at once?

Yes. Switch to Batch lookup and paste up to 100 addresses separated by new lines, commas, or spaces. Every valid address comes back in one table you can export as CSV or JSON.

Is this IP lookup free?

Yes. It is free to use and needs no account. A batch contains at most 100 addresses because that is the limit for one request.

Can an IP address reveal my home address?

No. An IP maps to an approximate area and to the network operator, not to a person or a street address. Treat geolocation as a rough location, never as identity.

What is an ASN?

An Autonomous System Number identifies the network that announces an address, such as an ISP, a hosting provider, or a large company. It is a good signal for whether traffic is residential or from a data center.

Does it support IPv6?

Yes. IPv4 and IPv6 are both supported in single and batch mode. IPv6 is normalized before comparison, so compressed, expanded, and case-only forms of the same address are counted once.

Can I export the results?

Batch results export to CSV for a spreadsheet or to JSON for a script, and any single result copies to the clipboard as plain text.

Why does a private IP like 192.168.1.1 show no location?

Private, loopback, and reserved ranges are not routed on the public internet, so no database can place them. The tool recognizes them in your browser and labels them instead of running a lookup.

What does the accuracy radius mean?

It is the radius, in kilometers, of the circle the real location is expected to fall within. A small radius points to a specific area; a large one means the result is only a broad regional estimate.
