Network Tools
Free tools for checking your IP, looking up DNS records, measuring latency, and estimating your connection speed — all running in your browser.
About network tools
Network tools answer everyday questions about your connection: what's my public IP?, is this domain actually resolving?, why does this site feel slow? They're the sort of checks you'd reach for before joining a video call, setting up a new domain, or troubleshooting a flaky Wi-Fi connection.
All four tools below run from your browser. The IP and DNS tools need a small server or public endpoint to respond to your request — we explain exactly what's sent on each tool's page. The latency and connection-quality tools only measure response times to public endpoints (Cloudflare, Google, GitHub); no data beyond standard request metadata leaves your device.
None of these tools require an account, a download, or an app. Open the page, get the answer, close the tab.

Frequently asked questions
Do these tools work on mobile?
Yes. Every tool is a single page built to load and respond quickly on any device. The IP, DNS, ping, and connection-quality tools all run on iOS and Android browsers without any extra setup.
Can I use these to check if my VPN is working?
Yes — the What is my IP tool is the quickest check. If the IP it reports matches your VPN provider's region rather than your home ISP, the VPN is routing traffic as expected.
Why would I use these instead of a command-line tool?
For quick one-off checks from any device, a browser tool is faster than opening a terminal — especially on mobile, or on a machine you don't own. These tools aren't meant to replace dig or ping for serious diagnostic work; they're for fast answers.
Is anything logged when I use a network tool?
Standard web server logs record your IP and the URL you requested briefly, for security and debugging. No tool input beyond that (e.g. the domain you look up) is retained on our side. Full detail is on the privacy policy.
