Network privacy diagnostics
Free IP checker, VPN protection test, DNS leak test, and browser fingerprint scan.
Run quick tests before using a VPN, proxy, travel network, or privacy-focused browser. Results stay in your browser except for the public lookup APIs needed to perform each test.

DNS leak test
Resolver visibility
Browsers cannot directly read your operating system DNS servers. This test compares public resolver responses and checks whether DNS-over-HTTPS endpoints reveal resolver metadata. A full commercial DNS leak test needs a backend with authoritative DNS logging.
Run the test to inspect available resolver signals.

Assessment
Run the check to estimate visible VPN protection.
The score combines public IP identity, DNS resolver signals, WebRTC exposure, and browser locale consistency. A full VPN audit still needs backend DNS logging.

How it works
Network privacy tests built for quick, readable results
IP lookup
The site requests public lookup services to show the IP address, network, approximate city, country, ASN, and timezone visible to websites you visit.
DNS visibility
Frontend-only DNS tests are limited by browser security. For the strongest leak detection, deploy a server endpoint that creates a unique hostname and records which resolver queries it.
VPN protection
The score checks whether public IP, DNS resolver, WebRTC, timezone, and language signals look consistent or expose information that a VPN user may want to review.
Fingerprinting
Browser, display, language, timezone, hardware, canvas, and WebGL signals are combined into a local hash so visitors can see how distinctive their browser appears.
FAQ
Questions people ask before trusting a VPN
What does the VPN protection score measure?
The score estimates visible browser-side VPN protection by checking public IP identity, DNS resolver signals, WebRTC exposure, timezone consistency, and browser language region.
Can a browser-only DNS leak test detect every DNS leak?
No. Browser-only DNS checks can compare public resolver signals, but a complete DNS leak test needs a backend with authoritative DNS logging for unique test hostnames.
Does NetScope store fingerprint results?
The browser fingerprint hash is calculated locally in the visitor's browser. Public lookup APIs are only used for the network tests needed to show IP and DNS-related signals.
Privacy guide
What to do if something looks exposed
Your IP shows the wrong region
Reconnect your VPN, choose a closer server, clear browser proxy settings, and rerun the IP check.
DNS data does not match your VPN
Enable the VPN provider's private DNS option, disable split tunneling for the browser, and retest.
Your fingerprint looks highly unique
Reduce extensions, use a mainstream browser profile, avoid uncommon fonts, and keep privacy settings consistent.
