About whatismineip.com
whatismineip.com is a free, no-nonsense toolkit for understanding your internet connection. At its heart is an instant IP address checker, but the site has grown into a small library of network utilities and plain-English guides that answer the questions people actually ask about IP addresses, privacy and home networking.
We built it because most "what is my IP" sites are cluttered, confusing, or quietly upsell you before answering the simple question you came for. Our goal is the opposite: show you the answer immediately, explain what it means clearly, and give you genuinely useful tools — without accounts, paywalls or dark patterns.
What you'll find here
Our approach
- Privacy first. Wherever possible, our tools run entirely in your browser. Our PDF tools, password and QR generators, hash and image tools never upload your files or data to any server — the work happens on your own device. Our IP checker shows your address back to you and doesn't build a profile of you. See our privacy policy for the full detail.
- Tested, not guessed. The logic behind our calculators (subnet maths, IPv6 expansion, range conversions) is unit-tested against known values. When a tool gives you an answer, we've checked it produces the right one.
- Plain English. Networking is full of jargon. Our guides explain concepts — IP addresses, DNS, IPv4 vs IPv6, IP privacy risks — the way we'd explain them to a friend, not a network engineer.
- Free and open access. No sign-up, no email wall, no trial. The site is supported by advertising, which lets us keep every tool free for everyone.
Who runs it
whatismineip.com is built and maintained by the small team behind OnlyVPN, a privacy and networking product. Working on VPN and network infrastructure means we spend our days with IP addresses, DNS, routing and the practical realities of online privacy — and this site is where we share those tools and that knowledge with everyone, for free. We do also mention OnlyVPN where a VPN is genuinely the right answer to a reader's question (for example, hiding your IP address), because it's honestly relevant — but every tool and guide here stands on its own and requires nothing from you.
How we're funded
This site is free to use and supported by display advertising. Ads let us cover hosting and development costs while keeping every tool and article open to all. We aim to keep advertising unobtrusive and never let it get in the way of the tool or content you came for.
