An IP proxy detection database is a collection of specialized data related to proxies and VPNs. It is a valuable tool for organizations that need to protect their online infrastructure from harmful incoming traffic.
IP proxy detection database uses several different techniques to identify a user’s connection as being originating from a proxy or VPN. These techniques include IP geolocation, reverse DNS lookup, and TCP fingerprinting.
Reverse DNS Lookup: This technique checks a user’s IP address against a database of known IP addresses used by VPN and proxy services. If an IP address matches the list of data centers that host these services, it is likely to be associated with a proxy service.
How IP Proxy Detection Databases Work and Why They are Important for Cybersecurity
Residential Proxies: These are IP addresses assigned to residential networks and are often more difficult to detect than data center addresses because they are not typically owned by an internet service provider (ISP). Fraudsters have to either pay a premium for these proxies or find illegitimate ways to acquire them.
WebRTC & Proxy Tests: In addition to checking whether an IP address is using a VPN, check if the user’s browser is using WebRTC. This is an interesting method because it allows you to test whether a user’s original IP address has been leaked by a proxy.
IP2Location Global IP Proxy Detection: This data set consists of a large amount of proxy IP address information from 248 countries worldwide. It is ideal for businesses that want to protect their infrastructure from proxy-related attacks and data breaches.
