Tool Overview

This tool looks up an IP address or domain and shows where it is, who provides it, and a map. You enter an IP or domain (or leave the box empty to see your own IP) and get location, provider, and connection type.

When you see an IP in logs, emails, or forms you often want to know where it is and who owns it. Doing that by hand means using several sites or commands. This tool does one lookup and shows the main details in one place.

It is for developers, support staff, and anyone who needs to check an IP or domain. You can use it with no special skills; just type an IP or domain and tap Lookup.

Background and Concepts

An IP address identifies a device or network on the internet. Domains (e.g. example.com) point to IPs. Services that know IP ranges can often say which country, region, or city an IP is in, and which provider or organization owns the block. That data is approximate: it usually reflects the provider or gateway, not the exact building. A related operation involves calculating subnet masks as part of a similar workflow.

Lookups are used for security, support, and debugging. You might check where a login or request came from, or whether an IP is from a home connection or a data center. Doing that manually means opening multiple tools. This tool sends your query to one service and shows the result: location, coordinates, provider, autonomous system (ASN), timezone, and flags such as mobile, proxy, or hosting.

The tool does not run on your server. You enter an IP or domain in the browser; the browser sends it to an external lookup service. The service returns data and the tool shows it and draws a map from the coordinates. If you leave the input empty and tap Lookup, the tool looks up the IP that the service sees (your own public IP).

Key Features

• IP or domain input. You can enter an IPv4 address, an IPv6 address, or a domain name. The tool checks the format and sends it to the lookup service. If you leave the input empty and tap Lookup, the tool looks up your own public IP. So you can check any IP or domain or your own IP in one place.
• Geolocation. The tool shows country, region, city, and zip (when the service returns them). It also shows latitude and longitude and uses them to draw a map. So you get a rough location and a map in one view.
• Map. When the lookup returns valid coordinates, the tool shows a small map centered on that point. The map is loaded from an external map service. So you can see the approximate area without leaving the page.
• Provider and ASN. The tool shows the network or ISP name (organization) and the autonomous system number (ASN) when the service returns them. So you can see who owns the IP block.
• Timezone. The tool shows the timezone associated with the IP (e.g. America/New_York). So you know the local time zone for that location.
• Connection type flags. The tool shows whether the IP is tagged as mobile, proxy (or VPN), or hosting (data center) when the service returns those flags. So you get a hint about the type of connection.
• Accuracy insight. The tool uses the proxy, hosting, and mobile flags to set a confidence level (High, Medium, or Low) and a short reason. It also shows expandable details (e.g. VPN or data center means location may reflect the server, not the user). So you understand how reliable the location might be.
• Copy and refresh. You can copy the looked-up IP to the clipboard. You can change the input and tap Lookup again to look up another IP or domain. So you can reuse the result or run multiple lookups.
• Optional analysis. When a lookup succeeds, you can request an optional text analysis of the IP data (e.g. summary or context). This may send the lookup result to another service. Use it only if you are comfortable sharing that data.

Common Use Cases

Logs and support. An IP appears in server logs or a support ticket. You want to know where it is and who provides it. Enter the IP (or domain if that is what you have), tap Lookup, and check location, provider, and connection type. For adjacent tasks, checking your IP address addresses a complementary step.

Security and abuse. You see an IP in an email, form, or firewall log and want a quick check. Look up the IP and see country, provider, and whether it is tagged as proxy or hosting. Use that as one input; do not rely on it alone for blocking or decisions.

Your own IP. You need your public IP (e.g. for whitelisting or debugging). Open the tool, leave the input empty, and tap Lookup. The tool looks up the IP that the service sees and shows the same details and map.

Domain check. You have a domain and want to see where it points. Enter the domain and tap Lookup. The service resolves it to an IP and returns location and provider for that IP. When working with related formats, looking up MAC addresses can be a useful part of the process.

Learning. You want to see how IP geolocation and provider data look. Enter a known IP or your own and explore the map, ASN, and confidence info.

How to Use This Tool (Step-by-Step)

1. Open the IP Address Lookup page in your browser.
2. When the page loads, the tool automatically looks up your own public IP (as seen by the lookup service). You see a loading message, then the result: IP, location, map, provider, and flags.
3. To look up another IP or domain, type it in the input box. You can enter an IPv4 address (e.g. 192.0.2.1), an IPv6 address, or a domain name (e.g. example.com). Maximum length is 255 characters. Tap Lookup (or press Enter).
4. Wait for the result. The tool sends your query to an external service and shows the response. If the format is wrong or the service fails, an error message appears. Fix the input or try again.
5. When the lookup succeeds, you see the IP (or resolved IP for a domain), city and region and country, a confidence level (High, Medium, or Low), and an optional Accuracy Info section you can expand. Below that you see network/ISP, ASN, type flags (Mobile, Proxy/VPN, Hosting), and a map. At the bottom you see region code, zip, timezone, and organization.
6. Use the copy button next to the IP to copy it to the clipboard. Change the input and tap Lookup again to look up another IP or domain.
7. Optionally tap Get Analysis to request a text analysis of the lookup result. This is optional and may send the data to another service.

Calculations and Logic

The tool does not compute location or provider itself. It asks an external service for the data.

Your input is trimmed and checked. If it is empty, the tool calls the lookup service with no query so the service returns data for the IP that made the request (your public IP). If you entered an IP or domain, the tool encodes it and sends it to the service. The service returns a JSON object with fields such as IP, country, region, city, zip, latitude, longitude, timezone, organization, ASN, and flags (e.g. mobile, proxy, hosting). The tool maps those fields to its own format and validates that required fields and coordinates are present. It then computes an accuracy insight: if the response says proxy or hosting, the confidence level is Low and the reason mentions VPN/proxy or data center; if it says mobile, the level is Medium; otherwise the level is High (residential or fixed). Each level has a short reason and a list of detail lines (e.g. that location may reflect the gateway, not the user). The result and the coordinates are shown on the page; the map is loaded from an external map service using the latitude and longitude. No secret or key is required for the lookup. If the service returns an error or the request times out, the tool shows an error message. In some workflows, performing DNS lookups is a relevant follow-up operation.

Tips, Limitations and Best Practices

Format. The tool accepts IPv4, IPv6, or a domain name. Invalid format is rejected before the request is sent. Use a valid IP or domain to avoid errors.

Empty input. Leaving the input empty and tapping Lookup looks up the IP that the external service sees. That is usually your public IP. If you are behind a VPN or proxy, it is the exit IP.

Location is approximate. Geolocation is based on provider and routing data. It often points to a city or region, not a street address. VPNs and proxies show the location of the exit server, not the user. Use the confidence level and Accuracy Info to judge how much to trust the location. For related processing needs, testing responsive layouts handles a complementary task.

No threat or blacklist check. The tool shows location, provider, and connection-type flags from one lookup service. It does not check if the IP is on a blocklist or threat database. Use other tools if you need abuse or threat data.

No hostname or abuse contact. The tool does not show hostname, reverse DNS, or abuse contact details. It shows what the lookup service returns: IP, location, provider, ASN, timezone, and flags.

Privacy. When you look up an IP, that IP and the result are visible in your browser. If you use the optional analysis, the lookup result may be sent to another service. Do not use the tool or analysis with data you need to keep private.

Errors and limits. The external service can be slow or down. If the request times out or the service returns an error, the tool shows a message. Try again later or try another IP. Rate limits may apply on the service side.
