PLogs is an IP intelligence and network-security service for detecting VPNs, proxies, Tor exits, datacenter addresses and other anonymized network traffic.
Instead of relying only on static IP blacklists, IPLogs combines multiple intelligence sources with active network analysis. Its detection system uses IP reputation data, ASN classification, TCP/IP and TLS fingerprints, RTT analysis, client signals and active protocol probes for technologies including OpenVPN, WireGuard and IKEv2.
Developers can use the public REST API to check IPv4 or IPv6 addresses and receive a verdict, risk score, confidence level, IP metadata and the individual signals that contributed to the result.
IPLogs can be used for fraud prevention, account security, bot and scraper detection, geo-content enforcement, ad-fraud analysis, security research and compliance monitoring.
The public API can be used without creating an account or obtaining an API key.
Listed in
VPN Detection
Detects known and suspected commercial VPN exit IPs.
Proxy Detection
Identifies proxy infrastructure and suspicious proxy-related network signals.
Tor Detection
Checks IP addresses against frequently refreshed Tor exit-node data.
IP Intelligence
Returns information such as IP address, ASN, organization, country, city and network classification.
Multi-source Detection
Cross-references multiple VPN providers, threat-intelligence feeds and network datasets.
Active Network Probing
Uses active probes for protocols including OpenVPN, WireGuard and IKEv2 instead of relying exclusively on IP lists.
IPv4 and IPv6 Support
Both IPv4 and IPv6 addresses can be analyzed.
Signal Transparency
API responses expose the signals contributing to a detection instead of only providing a black-box result.
REST API
Provides developer-friendly JSON API endpoints for individual and bulk IP checks.
No Registration Required
The public API can be used without creating an account.
No API Key Required
Normal public API usage does not require an API credential.

IPLogs combines multiple detection methods instead of relying on a single IP blacklist. It uses IP intelligence, TCP/IP and TLS fingerprinting, RTT analysis, active VPN protocol probing, client signals, and network checks to detect VPNs, proxies, Tor, and datacenter IPs. It also shows the individual signals behind every verdict, supports IPv4 and IPv6, and provides a free API without signup or an API key.
IPLogs is free to use, requires no account or API key, and provides transparent detection results instead of only returning a black-box risk score. Developers can see which signals and sources triggered a detection, use both IPv4 and IPv6, perform bulk IP checks, and integrate the REST API directly into their applications.
IPLogs is primarily built for developers, security teams, SaaS companies, fraud-prevention teams, website owners, and researchers who need to identify VPNs, proxies, Tor exits, datacenter IPs, or suspicious network traffic. Common use cases include fraud prevention, account security, abuse detection, geo-restriction enforcement, and network analysis.
IPLogs was created after finding that many VPN detection APIs marketed as free still required signup, imposed restrictive limits, hid detection signals behind paid plans, or produced unreliable results for services such as Apple Private Relay. The goal was to build a simple IP intelligence service that developers could use immediately without an account or API key, while also showing exactly why an IP was classified as suspicious. IPLogs launched in early 2026 and is developed by DigitalD.tech.

We have collected here some useful links to help you find out if IPLogs is good.
Check the traffic stats of IPLogs on SimilarWeb. The key metrics to look for are: monthly visits, average visit duration, pages per visit, and traffic by country. Moreoever, check the traffic sources. For example "Direct" traffic is a good sign.
Check the "Domain Rating" of IPLogs on Ahrefs. The domain rating is a measure of the strength of a website's backlink profile on a scale from 0 to 100. It shows the strength of IPLogs's backlink profile compared to the other websites. In most cases a domain rating of 60+ is considered good and 70+ is considered very good.
Check the "Domain Authority" of IPLogs on MOZ. A website's domain authority (DA) is a search engine ranking score that predicts how well a website will rank on search engine result pages (SERPs). It is based on a 100-point logarithmic scale, with higher scores corresponding to a greater likelihood of ranking. This is another useful metric to check if a website is good.
