About IP Tester

What Is IP Tester?

IP Tester is a free, privacy-focused network diagnostic website designed to help internet users understand their online connection details and browser privacy. Our tools provide instant, useful information about your IP address, DNS configuration, WebRTC exposure, and browser fingerprint.

Our Mission

We believe that understanding your online privacy shouldn't require technical expertise or expensive software. IP Tester provides clear, accessible tools that anyone can use to check their network privacy and learn about how internet addressing works.

What Our Tools Do

• IP Detection & Lookup — identify your public IP address and its associated geographic and network information
• DNS Leak Test — check whether your DNS queries are resolving through expected servers
• WebRTC Test — detect whether your browser is exposing local IP addresses
• Browser Test — view the information your browser shares with websites
• User Agent — see and understand your browser's user agent string
• DNS Lookup — query DNS records for any domain name

Our Privacy Approach

IP Tester is designed with privacy in mind:

• We do not store your IP lookup results or browsing data
• We do not use tracking cookies or analytics by default
• We do not sell or share any user data
• Our geolocation APIs process your IP temporarily and discard it
• Our cookie consent system gives you control over non-essential features

Limitations

IP-based tools have inherent limitations. IP geolocation is approximate and cannot pinpoint exact locations. VPN and proxy detection relies on database matching that may not cover all services. Privacy scores are simplified indicators, not comprehensive security assessments.

We strive to be transparent about what our tools can and cannot tell you, and we clearly label limitations and uncertainties in our results.
