General questions

We have accumulated a vast array of non-residential Autonomous Systems with the help of contributors, robots and our team! We have a large portion of the web mapped out already, and only plan to keep expanding. If you notice an inaccuracy, we would appreciate if you kindly contact us. Proxies and Tor nodes are automatically updated on a hourly basis based on data reported from thousands of internet services (e.g.: game server bruteforce attempts and website logs).
Our API offers the ability for the user to handle their own 'risk-level' by returning a 'block' variable that varies regarding the queried IP address. This is self-explanatory if you read our API usage documentation.
Yes, you can lookup IPv6 addresses.
Not yet, but we have some ideas floating around. Leave us a message to show your interest if that's the case.
IPHub V1 has reached end-of-life. Please migrate to IPHub V2.

Yes, we block search engine crawlers. This essentially means that your website will be delisted from search engines if you block proxies on your website upon page landing. We recommend you to check login/registration pages instead.

Billing questions

We use Paddle for subscription handling. They support most credit cards and PayPal, as well as some regional payment methods if available.
Leave us a message if you would like to use another payment method, we'll see what we can do.
Usually your key will be emailed to your inbox automatically upon payment. If it does not appear in your inbox, please check your spam box and other email folders before contacting us.
If you're subscribing to a free plan, please note that you need to register, verify your e-mail address, and only then claim the free API key.
Yes, you can cancel your subscription renewal anytime. Please note that this doesn't automatically entitle you a refund for any unused days. You'll have to contact us for that.

API questions

We have multiple API nodes and two front-facing load balancers. If a load balancer fails DNS-based failover kicks in. Downtime should not exceed 5 minutes. Make sure your app doesn't crash if the API goes down.

You may want to check our API documentation website, where you can find some code examples.

Yes, but due to data saturation we don't recommend caching for more than 24 hours. Critical applications should cache for a maximum duration of 1 hour.
