Whatismytools

Whatismytools offers a collection of 16 free browser-based diagnostic tools designed to provide users with instant information about their network, device, and connection. The platform focuses on quickly revealing details such as public IP address, internet service provider, DNS records, latency, network type, browser information, and internet speed, all without requiring user registration or sign-up.

Among its capabilities, Whatismytools allows users to view their public IPv4 and IPv6 addresses, along with associated ISP, city, and country data. It includes a tool to identify the organization linked to a public IP and connection, as well as a DNS lookup feature that queries A and AAAA records using Cloudflare DNS over HTTPS. Users can measure HTTPS round-trip time as a practical browser-based latency check, and the service detects network type—such as Wi-Fi, cellular, or ethernet—while estimating bandwidth and speed class using the Network Information API.

Privacy-related diagnostics are also available. The platform compares HTTP-visible public IP addresses with WebRTC ICE reflexive addresses to help identify potential IP leaks and provides context for DNS leaks in plain language. An in-browser speed test measures both download and upload speeds, and there are tools for detecting browser name and other device characteristics. The tools are accessible directly from the browser and deliver immediate results.

Whatismytools is intended for anyone needing quick, registration-free insights into their network, connection, and device environment. The service is free to use, supported by ads and analytics as explained in its privacy policy. It is positioned as a suite of browser diagnostic tools for network, privacy, and device information.
