NetPeek - IP & Leak Test
Check your public IP address, run a browser privacy leak test, test WebRTC exposure, and lookup IPv4 or IPv6 addresses.
Run an IP leak test, WebRTC leak test, timezone check, language check, browser fingerprint surface check, storage check, Do Not Track check, Global Privacy Control check, Canvas/WebGL check, and DNS leak limitation review. This browser-based test displays results to you and does not create a tracking ID.
Public IP Exposure
LoadingThis shows the public IP address websites can see, including ISP, ASN, approximate location, and proxy/VPN signals when available.
Your public IP check will appear here after the app loads basic IP details.
Fix: Use a VPN or proxy if you do not want websites to see your normal public IP address.
WebRTC Leak Test
Not testedWebRTC can sometimes expose local or alternate network addresses. This check runs only after you click Run Leak Test.
WebRTC leak results will appear here after the test runs.
Fix: Use a VPN with WebRTC leak protection or disable WebRTC exposure in your browser or extension settings.
Timezone & Language
Not testedTimezone and browser language can reveal location clues even when your IP is masked.
Timezone and language comparison results will appear here after the test runs.
Fix: Match your browser timezone and language to your VPN/proxy location when privacy consistency matters.
Browser & Device Signals
Not testedBrowser, platform, screen size, viewport, pixel ratio, and touch support can reveal device clues.
Browser and device details will appear here after the test runs.
Fix: Use privacy-focused browser settings or a hardened browser profile to reduce fingerprinting signals.
Privacy Controls & Storage
Not testedCookies, localStorage, sessionStorage, Do Not Track, and Global Privacy Control can affect tracking behavior.
Privacy control and storage results will appear here after the test runs.
Fix: Use private browsing, block third-party cookies, clear site storage, or enable privacy signals when supported.
Canvas / WebGL Surface
Not testedCanvas and WebGL can expose graphics capabilities that may contribute to browser fingerprinting.
Canvas and WebGL availability will appear here after the test runs.
Fix: Use anti-fingerprinting browser settings or extensions if you want to reduce graphics-based signals.
DNS Leak Limitation
LimitedA true DNS leak test requires controlled DNS test domains or a DNS leak API. This backend-free app can explain the limitation and check for mismatch clues.
DNS leak limitation note will appear here after the test runs.
Fix: Use a VPN with DNS leak protection and test DNS leaks with a dedicated DNS leak service if needed.
The My IP tab displays your public IP address, IPv4 or IPv6 detection, hostname, ASN, ISP, city, region, country, approximate map location, and basic privacy signals such as proxy, VPN, Tor, relay, or hosting detection when available.
Your IP Details
Results update automatically after the app checks your current public network connection.
Use the IP Lookup tab to search a public IPv4 or IPv6 address and view network details such as hostname, ASN, ISP, country, region, city, approximate map location, and basic privacy signals.
