Our mission
WhatIP exists to answer practical questions about the internet and everyday numbers without making you sign up, install anything, or wade through a dozen pop-ups first. We build fast, honest tools that run in your browser and explain what they do, so you understand the result instead of just staring at it. If a question has a clear answer, we want WhatIP to give it to you in a couple of seconds.
What WhatIP is
WhatIP is a free hub of four kinds of tools.
Network tools. This is where the name comes from. We help you find your own public address with What's My IP, look up the location and network owner behind any address with IP Lookup, resolve records with DNS Lookup, check mail routing with MX Lookup, and pull registration details with WHOIS. These tools are useful for troubleshooting a home connection, checking that a domain is configured correctly, or simply satisfying curiosity about how the internet is wired.
Calculators. We cover the money and health math people search for most: mortgage payments, loan amortization, salary and income tax estimates across many regions, BMI, and more. Each calculator uses the same standard formulas a professional would use, validated against published reference cases.
Browser games. We host a small, growing set of playable games that run entirely in the browser. They are free, need no download, and carry no account.
Crowdsourced phone-number lookups. Visitors can report and read notes about unknown phone numbers, which helps the next person decide whether to pick up. This section grows from community contributions, so treat entries as opinions rather than verified facts.
Who we are
WhatIP is maintained by a small group we call the WhatIP Editorial Team, a mix of people with software engineering and writing backgrounds. We test our tools, audit the content for clarity, and keep reference values current. We do not invent expert personas or borrow credentials we do not have. You can read exactly how we build, source, and review everything in our editorial guidelines.
How we make money
WhatIP is supported by display advertising served through Google AdSense. That is the whole business model. We do not sell your personal data to anyone, we do not push affiliate links into the body of our content, and we do not let advertisers influence the results a tool produces or the order in which anything is presented. An ad you see is a programmatic placement chosen by the ad network, not an endorsement by us. If our funding model ever changes, we will say so plainly on this page.
How we keep things accurate
Every calculator is checked against published reference cases before it ships, and network tools are tested against known inputs. Tax brackets and rates are reviewed each year as official figures are released, so a page may briefly show last season's numbers right after a change. Where a result depends on a third-party data source, such as IP geolocation or WHOIS records, the underlying data can be cached or incomplete, and we say so. The full process, including how to report a mistake, lives in our editorial guidelines.
Our privacy stance
The tools and calculators run in your browser. When you type an address into a calculator or run a lookup, we are not building a profile of you, and calculator inputs are not stored on our servers. We keep the data we touch to a minimum and explain the rest in the privacy policy, including the cookies that advertising and analytics rely on. The short version is simple: use the site, get your answer, move on, with no account required.
