Proxy IP Checker

Why Check for Proxies and VPNs?

Proxies and VPNs are commonly used to mask real IP addresses. While these tools have legitimate uses, they are also used to bypass security measures, commit fraud, or scrape data.

Our Proxy IP Checker helps you detect these connections in real time, making it easier to prevent unauthorized access, block suspicious logins, and ensure your users comply with your platform’s policies.

How It Works

The Proxy IP Checker uses a global database of VPNs, proxies, and Tor nodes that is updated in real time to ensure accurate detection. Here’s what it checks:

• Proxy Status: Identifies datacenter IPs, transparent proxies, and Tor nodes.
• IP Geolocation: Pinpoints the approximate location and ISP of the IP.
• Connection Type: Distinguishes between residential, mobile, and datacenter IPs.
• Blacklist Status: Detects if the IP is flagged in major threat intelligence databases.

Customizable Risk Scoring – Tailor Detection to Your Needs

Not all proxies or VPNs pose the same level of risk. That’s why AbstractAPI’s Proxy IP Checker includes customizable risk scoring to give you greater control.

What is Customizable Risk Scoring?

Risk scoring allows you to assign different weightings to certain connection characteristics—such as IP location, ISP type, or blacklist status—to determine the overall risk level of an IP.

For example:

• High-Risk Proxy: Datacenter IPs associated with known bot traffic.
• Moderate-Risk Proxy: Residential proxies used for bypassing content restrictions.
• Low-Risk Proxy: IPs with an unclear history but from an unknown mobile network.

Benefits of Customizable Risk Scoring:

• Granular Control: Tailor detection thresholds to fit your security needs.
• Automated Responses: Trigger specific actions based on different risk scores (e.g., blocking, 2FA requests, or temporary access).
• Industry-Specific Flexibility: Customize for specific use cases, whether for fraud prevention, streaming, or SaaS login protection.

With customizable risk scoring, your app can dynamically adjust how it handles each IP—allowing for smarter, more precise proxy detection.

Frequently Asked Questions

What is a proxy or VPN?

A proxy or VPN routes your internet connection through an external server, masking your real IP address.

Why is my IP detected as a proxy when I’m not using one?

Datacenter or shared IPs are sometimes flagged as proxies. Consider using a static, residential IP for a more stable result.

Can I check multiple IP addresses at once?

Yes! You can bulk-check IP addresses via our API to detect VPNs, proxies, and Tor nodes at scale.
