Terms of use

Last updated 31 August 2026

This is a service run by one person, free at its lowest tier and paid above it. Treat what it tells you as an informed estimate to check before you act on it, never as a fact established about anybody.

Who provides this

This site is run by a private individual in the Netherlands. Contact: [email protected]. Using the site means accepting these terms.

What it does

It answers questions about IP addresses and networks: which network an address is in, who a block is registered to, roughly where it is, and whether public sources describe it as VPN, proxy, datacenter or previously reported space. It also publishes aggregate statistics about networks, operators, registered organisations, countries and VPN providers. There is a JSON API that returns the same answers. Every plan returns the same fields; what a paid plan buys is a larger allowance, more API keys, and the batch and full-breakdown routes. The current plans and prices are on the pricing page.

Accuracy, and its limits

This matters more than anything else on this page, so it comes first.

  • Location is an estimate for a block of addresses. It is not the location of a device or a person. Two sources are asked, and a city is published only where they name the same country. Where they disagree, the country is given, the city is withheld, and the other reading is shown beside it.
  • Registration is a registry fact, not a physical one. Who a block is registered to and where its space is used are different questions and frequently have different answers.
  • Reputation entries describe an address block at a point in time. Addresses are reassigned. A listing from months ago may say nothing about whoever holds the address now, which is why the date it was last confirmed is shown.
  • VPN, proxy and datacenter signals come from published lists that are incomplete and sometimes wrong. An address absent from every list is not proven to be residential.
  • The two scores are summaries of those signals, not verdicts. They indicate what public sources say. They do not establish that anyone did anything.

Nothing here should be the sole basis for blocking a person, refusing a transaction, or any other decision that affects someone. If a result matters, verify it.

The service is supplied as it is, with no warranty of any kind. That includes any warranty that a result is accurate, complete, current or fit for a purpose you have in mind, and any warranty that the service will be available or uninterrupted. Data is drawn from public and third-party sources that contain errors, go stale, and change without telling us.

Deciding whether an answer is good enough for what you are doing with it is your responsibility, not ours. You choose what to do with a result. Where a wrong answer would cost you or somebody else something, check it against another source before acting, and build your own product so that a wrong or missing answer is survivable. This is the point of the whole page.

If something is wrong

If an entry about your network or organisation is inaccurate, write to [email protected] saying which address block you control and what is wrong. Corrections are made where the underlying data allows. Much of the data comes from upstream sources, so some corrections have to be made with the source, and you will be told when that is the case.

Accounts

An account is free, raises the request limit, and is what a paid plan attaches to. Creating one asks for an email address and a password, and asks you to confirm that you are 16 or older and that you accept these terms. What is stored and for how long is in the privacy notice; what matters here is the conditions.

  • You must be at least 16. Where the law of the country you are in sets a higher age for entering an agreement like this, or requires a parent or guardian to agree on your behalf, that applies instead and it is your responsibility to meet it. An account we learn is held by somebody who does not is closed.
  • Give an address you can receive mail at, and give your own. The limit does not go up until the address is confirmed.
  • One account per person or business. Several accounts to hold several free allowances is working around the rate limit, which is the next section, and it is also a way of avoiding paying for a plan.
  • Keep your password and your keys to yourself. Anything done with them counts as done by you, and a key can be revoked from your account page the moment you think one has got out.

An account can be suspended or closed where these terms are broken, and suspended where a payment fails. You can close yours at any time from your account page, and download a copy of everything held about it first. The privacy notice says exactly what closing it deletes and what it strips instead.

Plans and payment

Plans, prices and what each one includes are on the pricing page, and that page is part of these terms. Prices are in US dollars and exclude VAT and any other tax, which is added at checkout where it applies.

  • Our payment provider takes the payment and is the seller on it. Your purchase is a contract with them, and their terms and their refund handling apply to the payment itself. Their name, not ours, is what appears on your statement. We never see or hold your card details.
  • A plan is monthly or yearly and renews automatically at the price then published, until it is cancelled. A year is charged at ten months.
  • The allowance is per day and it does not roll over. An unused day is not credited, kept, or refundable. Where you need more than a plan allows, move up a plan or write to us.
  • Prices can change. A rise takes effect at your next renewal and not during a period you have paid for, and you will be told at least 30 days before it does, so you can cancel first.
  • Non-payment suspends access. If a payment fails we may suspend the account until it is settled. Your data is not deleted for this.

The free plan is not for commercial use

The free plan is for evaluation, for learning, and for things nobody pays you for. Using it inside a product, a service or an operation that you charge for, or that a business you work for relies on, needs a paid plan.

This is a condition of use rather than a technical limit, so it is stated here and enforced here. If you are unsure which side of it you are on, write to us and ask: the answer is usually yes and the paid plans start at $9 a month.

Cancelling, and the 14 days

  • Cancel at any time from your account page. Cancelling stops the next payment. The plan keeps working until the end of the period you have already paid for, and then the account returns to the free plan.
  • Your first paid subscription can be cancelled within 14 days for a refund of the part you have not used, on a monthly plan and a yearly plan alike. What counts as used is worked out from the time elapsed and the lookups spent, and the arithmetic will be shown to you before the refund is confirmed.
  • After those 14 days, and on any later subscription, cancelling stops future payments and does not refund the current period.
  • Nothing here removes a right you have as a consumer under the law of the country you live in, including any right of withdrawal, and where that law gives you more than this section does, it is the law that applies.

Refunds are made through our payment provider, to the method you paid with. The refund policy sets out how the unused part is worked out and how to ask.

Using it fairly

The service is rate limited per address, and an account raises the limit substantially. Please:

  • do not work around the rate limits, whether by rotating addresses, opening several accounts, distributing requests or any other means
  • do not bulk-download the site or the API in order to rebuild the underlying database, and do not resell or redistribute the data itself. Building your own product on the answers and charging for that product is exactly what the paid plans are for; reselling our data as data is not, and neither is standing in front of the API and selling access to it
  • do not use the service to try to identify, locate or track an individual person, household or street address. This is our own condition. It was inherited from a data licence as well until that licence left the request path on 26 August 2026, and it holds either way
  • do not use it to attack, overload or interfere with the service or anyone else

Access may be limited or blocked where use threatens the service's availability or breaches these terms.

Availability, and what happens when it is down

There is no uptime commitment and no service level agreement, on any plan, including the paid ones. Paying for a larger allowance buys you a larger allowance. It does not buy an availability guarantee, and no figure for uptime is promised anywhere on this site or in any communication from us. If you need a contractual availability target, write to us before you buy rather than after.

The service may be slow, interrupted, taken down for maintenance, or changed. Features may be withdrawn. Data sources may become unavailable or unusable to us at short notice, and where that happens a field may empty or disappear. The API may change; where a change would break existing use, reasonable notice is given where that is practical.

Where an interruption is long enough to matter, we may credit or refund part of what you paid. That is at our sole discretion and it is not something you are entitled to demand. Ask, describe what happened and when, and it will be looked at honestly. A credit given once does not create a right to one next time and does not set any figure for the future.

We are not responsible for anything outside our reasonable control, including connectivity, hosting, upstream data providers, payment providers, denial of service attacks, and acts of government.

Liability

Read the accuracy section above first. This one says what follows from it.

We are not liable for what you do with an answer, or for an answer being wrong. That covers an address placed in the wrong country, a network attributed to the wrong holder, a VPN or proxy signal that is present when it should not be or absent when it should be, a score read as a verdict, a field that is empty, and data that was correct when published and has since gone stale.

So far as the law permits, we are not liable for indirect or consequential loss, loss of profit, revenue, business, goodwill or anticipated savings, loss or corruption of data, or the cost of getting substitute services, however caused.

Where we are liable, our total liability for all claims arising in any twelve month period is limited to the amount you actually paid us for the service in that period, or one hundred euro, whichever is greater. On the free plan that means one hundred euro.

None of this excludes or limits liability that Dutch law does not permit to be excluded or limited: for death or personal injury caused by negligence, for intent or deliberate recklessness, or for fraud. Nothing here affects any right you have as a consumer that cannot be limited by agreement, and if any part of this section is held to go further than the law allows, that part applies to the greatest extent the law does allow and the rest of these terms are unaffected.

Your side of it

You are responsible for what you do with the service and for anything done with your account or your keys.

If you use the service in the course of a business, you agree to cover us against claims, losses, and reasonable legal costs brought by somebody else and arising out of your use of the service or of what it returned, including any decision you took about a person on the strength of it. This paragraph does not apply to you if you are a consumer.

Where the data comes from

This site is built on public and licensed datasets, and some carry conditions that are passed on to you.

Location comes from the DB-IP Lite database, IP Geolocation by DB-IP, used under the Creative Commons Attribution 4.0 International licence, and from a second country dataset released into the public domain. A city is published only where the two agree on the country.

The announcing network and the operator name beside it come from a public-domain dataset built from routing data, which carries no attribution condition.

Other data comes from the regional internet registries, published network operator datasets, and openly published lists of VPN, proxy, datacenter and reported address ranges. Their terms are respected, including any restriction on redistribution. The site publishes counts, shares and named top entries, and never lists of individual addresses or ranges.

Changes to these terms

These terms may change. The date at the top shows when they last did. Continuing to use the service after a change means accepting it. Where you hold an account, a substantive change is shown to you on your account page, so a change you would care about does not pass unnoticed.

Where a change materially reduces what a paid plan gives you, it takes effect at your next renewal rather than during a period you have paid for.

Law and jurisdiction

Dutch law applies. Disputes go to the competent court in the Netherlands. If you are a consumer, this does not remove your right to the protection of the mandatory law of the country you live in, or to bring proceedings where the law entitles you to.

Privacy

What this site records about your visits is set out on the privacy page.
