Specialized detection engine identifying VPNs, proxies, Tor nodes, and residential proxies with threat scoring.
IP2Proxy focuses exclusively on proxy detection rather than trying to be a general-purpose geolocation service, allowing deep specialization in anonymizer identification. The platform detects an extensive range of proxy types: VPN servers, public proxies, web proxies, Tor exit nodes, data center ranges, and critically, residential proxies—which are notoriously difficult to identify because they route through legitimate ISP IP addresses assigned to homes. Residential proxy detection matters for fraud prevention as these services explicitly market themselves as "undetectable" to businesses.
Each detected proxy receives a threat level classification and fraud score based on historical abuse patterns and current intelligence. The service returns additional context like proxy type, when the IP was last seen operating as a proxy, and the confidence level of the detection. This risk scoring enables graduated response strategies—perhaps blocking high-risk IPs entirely while adding extra verification steps for moderate risks rather than blanket blocking all detected proxies.
Deployment options include downloadable databases for local lookups, a REST API for real-time checks, and a batch processing service where you upload IP lists and receive bulk results. The local database approach suits applications processing large volumes where per-query API costs would be prohibitive, while the API works better for real-time scoring during user registration or transaction processing.
IP2Proxy integrates with various platforms through pre-built widgets, provides bulk lookup through web upload, and connects with automation platforms like Zapier for workflow integration. The service maintains separate databases for IPv4 and IPv6, with regular updates to catch newly identified proxy infrastructure. For businesses combating account fraud, scraping, bonus abuse, or geographic restriction bypass, this focused solution often outperforms generic geolocation services with basic proxy flags.
Advanced fraud prevention platform claiming 40% better detection rates with minimal false positives.
IPQualityScore positions itself as the most accurate proxy and fraud detection service available, claiming 40% higher detection rates compared to competitors while maintaining extremely low false-positive rates.

The self-learning aspect means accuracy potentially improves over time as the neural network ingests more data points and refines its models. This contrasts with static database approaches requiring explicit manual updates. For applications where having the absolute latest geolocation data matters more than having extensively audited historical data, the neural network approach offers advantages. The trade-off is less documentation around accuracy methodology compared to providers publishing detailed testing results.
Specialized geocoding converting addresses to coordinates with comprehensive US and Canada coverage.
Geocodio focuses specifically on forward and reverse geocoding rather than IP geolocation—converting street addresses to coordinates (forward) and coordinates to addresses (reverse). While different from IP-based location services, Geocodio proves valuable for applications needing to correlate IP location data with physical addresses or enrich coordinate data with address details.
The service excels at US and Canadian address processing with high accuracy. Reverse geocoding "snaps" submitted coordinates to the nearest matching address, typically within a 500-foot threshold. The accuracy type indicator (rooftop, nearest_street, nearest_place) helps you understand precision levels. Batch processing supports up to 10,000 coordinates at once, efficient for bulk address validation or enrichment operations.
Data enrichment capabilities go beyond basic geocoding to include congressional districts, census tract information, and timezone data. This supplementary information proves useful for applications in political campaigns, demographic analysis, or regulatory compliance where knowing precise geographic boundaries matters. The spreadsheet enrichment feature allows uploading CSV files with addresses or coordinates and receiving enriched results with all requested data appended.
Pricing starts with 2,500 free lookups daily, sufficient for many small applications. Official client libraries for Ruby, Python, PHP, JavaScript, and command-line usage simplify integration. The API documentation is thorough with extensive examples. For applications needing to convert IP geolocation coordinates into street addresses, or validate address data from user input, Geocodio provides specialized capabilities that general IP geolocation services don't offer. The US/Canada focus means accuracy is highest in these markets.
Simplest possible approach to retrieving your public IP address with no bells and whistles.
ipify serves one purpose exceptionally well: returning your public IP address. The API is refreshingly simple—make a GET request and receive your IP in plain text, JSON, or JSONP format depending on your needs. No registration, no API keys, no complex parameters. The service handles both IPv4 and IPv6 addresses with separate endpoints for each or a combined endpoint that returns whichever address type your connection uses.
This simplicity made ipify remarkably popular, handling tens of billions of requests monthly at its peak. The service was created as a personal project but gained traction because retrieving your own public IP is a common requirement that shouldn't require authentication or complex setup. The lack of features is intentional—ipify does one thing and does it reliably at massive scale.
Common use cases include applications that need to know their public IP address for registration, configuration, or logging purposes. Dynamic IP users can run scripts checking their current IP and updating DNS records or notification systems when it changes. Network administrators use it for quick IP verification during troubleshooting. The JSONP support makes it accessible from client-side JavaScript despite cross-origin restrictions.
The service is free, has no rate limits on the public endpoint, and makes no attempt to monetize through premium tiers. Code examples exist for virtually every programming language and framework. For the specific task of "what is my public IP address," ipify remains the gold standard of simplicity. It doesn't provide geolocation, threat detection, or any intelligence about IPs—but that's not its purpose. For applications needing those capabilities, you'd use ipify to get the IP then pass it to a separate geolocation service.
Community-powered IP reputation database enabling reporting and checking of abusive addresses.
AbuseIPDB operates as a collaborative platform where system administrators and webmasters report IP addresses involved in malicious activity. The community-driven model means threat intelligence comes from actual victims of attacks rather than honeypots or theoretical data. The database tracks various abuse types: DDoS attempts, spam, fraudulent orders, hacking attempts, phishing, spoofing, SQL injection, and other malicious behavior.
The Confidence of Abuse score ranges from 0-100, indicating how confident the system is, based on user reports, that an IP is malicious. This percentage weighting helps distinguish between addresses with a single isolated report versus those with numerous reports from multiple sources. The distinct reporter count and recent report timing provide additional context for risk assessment.
Free API access allows 1,000 daily requests for both checking IPs and reporting abusive addresses. Verified webmasters receive 3,000 daily requests while supporters get 5,000. These rate limits accommodate most small to medium applications. The check API returns comprehensive data including confidence score, number of reports, last report date, ISP information, usage type, domain name, country, and top 20 detailed reports with comments from submitters.
The reporting functionality allows you to contribute back to the community database when detecting attacks against your systems. Fail2Ban integration tutorials help automate reporting of repeated failed login attempts and similar patterns. Web interface access has no usage limitations for manual lookups. The bidirectional model—both consuming and contributing threat intelligence—strengthens the overall database quality as more participants join. For businesses wanting to benefit from shared threat intelligence without expensive commercial feeds, AbuseIPDB provides substantial value.
