IP Address Details

Overview

IP Address Details offers a suite of APIs centered around IP address intelligence, enabling developers to integrate geolocation, network information, and threat detection capabilities into their applications. Founded in 2012, the platform focuses on providing granular data for individual IP addresses through a RESTful interface, returning information in JSON format. This service is primarily utilized for use cases such as tailoring website content based on a user's geographical location, detecting potential fraud by identifying suspicious IP origins like VPNs or proxies, and enhancing cybersecurity measures.

The core offerings include an IP Geolocation API that provides details like city, country, region, latitude, and longitude. Beyond basic location, the service extends to VPN/Proxy Detection, which helps identify if an IP address belongs to a known VPN, proxy, or Tor exit node. This particular feature is relevant for maintaining service integrity and mitigating risks associated with obfuscated traffic. Additionally, the ASN/ISP Lookup API supplies details about the Autonomous System Number (ASN), Internet Service Provider (ISP), and organization associated with an IP address, which is useful for network analysis and targeted advertising.

Developers working on applications requiring real-time IP data for content delivery networks (CDNs), e-commerce fraud prevention, or security monitoring can integrate these APIs. For instance, an e-commerce platform might use the geolocation data to display localized currency and shipping options, while simultaneously employing VPN/proxy detection to flag potentially fraudulent transactions originating from anonymous networks. The API's straightforward JSON response structure and concise API documentation aim to simplify integration for developers, focusing on practical implementation rather than complex configurations.

While IP Address Details provides geographic and network data, it differentiates itself by including specific detection for various types of anonymizing services. This specific focus on identifying VPN and proxy usage positions it as a tool for applications where understanding the true origin of a user's connection is critical. Compared to general-purpose geocoding services, its emphasis on threat intelligence via proxy detection offers a specialized layer of data for security-conscious applications. For example, a gaming platform could utilize this to prevent region-locked content bypass or to identify users attempting to circumvent bans via anonymous connections.

Key features

• IP Geolocation API: Provides precise geographical data for any IPv4 or IPv6 address, including country, region, city, zip code, latitude, and longitude. This enables applications to personalize content, localize services, and analyze traffic distribution based on user location.
• VPN/Proxy Detection API: Identifies if an IP address is associated with a known VPN server, anonymous proxy, or Tor exit node. This feature supports fraud prevention, content protection, and security policies by flagging suspicious or masked connections.
• ASN/ISP Lookup API: Retrieves information about the Autonomous System Number (ASN), Internet Service Provider (ISP), and organization details linked to an IP address. Useful for network analysis, understanding traffic sources, and B2B targeting.
• Threat Intelligence Data: Integrates data points to help assess the risk level associated with an IP, particularly concerning its use in anonymization services, aiding in real-time decision-making for security applications.
• RESTful API with JSON Output: Offers a standard, easy-to-parse JSON response format for all API requests, aligning with common web development practices.
• Free Daily Request Tier: Includes a free tier allowing up to 1,000 requests per day, suitable for testing and low-volume applications without immediate subscription.

Pricing

IP Address Details offers a free tier for basic usage, with paid plans scaling based on the number of monthly requests. The pricing structure is designed to accommodate various usage levels, from individual developers to larger enterprises requiring higher request volumes. Pricing details were accurate as of May 2026. For the most current pricing information, refer to the IP Address Details pricing page.

Common integrations

IP Address Details APIs can be integrated into various systems and workflows where IP intelligence is required. Examples include:

• Web Servers and CDNs: To serve localized content, apply region-specific access rules, or optimize content delivery based on user geography.
• E-commerce Platforms: For fraud detection by cross-referencing IP location with billing address and identifying suspicious transactions originating from VPNs or proxies.
• Marketing and Analytics Tools: To segment user bases by geographical location, analyze traffic patterns, and refine targeted advertising campaigns.
• Security Information and Event Management (SIEM) Systems: To enrich security logs with IP intelligence, aiding in identifying and responding to threats, especially those involving anonymized connections.
• Custom Application Development: Any custom application requiring IP-based access control, content personalization, or bot detection can use the API. For example, a survey platform might restrict participation based on country.
• CRM Systems: To enrich customer profiles with geographic data, enabling sales and support teams to provide localized assistance.

Alternatives

• IPinfo.io: Offers detailed IP data, including geolocation, ASN, company, and abuse contact information, with a focus on data accuracy and developer-friendly APIs.
• IP-API.com: Provides a free and paid JSON/XML IP geolocation API, known for its fast response times and global coverage, often used for content localization and visitor analytics.
• Abstract API: Offers a suite of APIs, including a robust IP Geolocation API that delivers precise location data, currency, and time zone information, designed for simplicity and scalability.
• Cloudflare Workers' cf object: For users already on Cloudflare, the cf object provides IP geolocation data directly within serverless functions at the edge, offering a highly performant alternative for edge-based applications.
• AWS WAF Geo Match: For AWS users, Geo Match conditions within AWS WAF can control access to content based on the geographic location of client requests, providing a network-level alternative for access control.

Getting started

To begin using the IP Address Details API, you typically need to sign up for an API key on their website. Once you have your key, you can make HTTP GET requests to the various API endpoints. The primary method involves sending an IP address as a parameter and receiving a JSON response. Below is a simple example using cURL to query the IP Geolocation API:

# Replace YOUR_API_KEY with your actual API key
# Replace 8.8.8.8 with the IP address you want to look up

curl "https://api.ipaddressdetails.com/v1/ip.json?apiKey=YOUR_API_KEY&ip=8.8.8.8"

A successful response for the geolocation endpoint for an IP like 8.8.8.8 (Google DNS) might look like this:

{
  "ip": "8.8.8.8",
  "country_code": "US",
  "country_name": "United States",
  "region_code": "CA",
  "region_name": "California",
  "city": "Mountain View",
  "zip_code": "94043",
  "latitude": 37.40599,
  "longitude": -122.078514,
  "time_zone": "America/Los_Angeles",
  "asn": "AS15169",
  "isp": "Google LLC",
  "organization": "Google LLC",
  "is_proxy": false,
  "proxy_type": null,
  "risk_score": 0
}

This output demonstrates the type of detailed information you can retrieve, including geographical coordinates, time zone, ISP, and a flag indicating if the IP is a proxy. For more specific queries, such as VPN/Proxy detection, you would use the dedicated endpoint documented in the IP Address Details API documentation.
