    Geolocation, Proxy, VPN or Tor exit address detection, for free.

    AS207111 provides a free Whois service for content customization, advertising, digital rights management, compliance, fraud & proxy detection, security and more.

    You will always have the most accurate location data available for every API request, without having to worry about maintaining a local database. For Proxy, VPN or Tor exit address detection, we use machine learning & probability theory techniques using large datasets from different sources with 11,500+ networks from 2,200+ privacy providers.


    The recommended way to install AS207111 Whois is through NPM.

    npm install @as207111/whois --save

    Getting Started

    First, request a free api access token from to get access to all api features, including all premium features, like privacy lookups.

    Then initialize a new client with your API Access Token and call the lookup method to lookup any IPv4 or IPv6 address.

    We recommend using the client only server-side, so that your API access token is not exposed.

    import {Client} from "@as207111/whois";
    // instantiate a new api client with your api acces token
    const client = new Client("xxx|xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx");
    // lookup a given ipv4 or ipv6 address
    const response = await client.lookup("2001:67c:770::");
    // display the response
