Give us an IP address or ASN, and we'll return detailed, evidence-based data about it, including who operates it, where it is, whether it's anonymized, and more. Here’s more information on our available datasets:
- Abuse Contact Data — Perfect for combating malicious activities, our abuse contact data provides the abuse contact information for every publicly available IP address on the Internet.
- ASN Data — Our standard API returns ASN information, including the AS number, registry name, domain, and type (i.e., whether it’s a hosting, ISP, educational, government, or business ASN). We also provide a dedicated ASN API which provides access to detailed ASN data, including related domains, allocation date, registry name, the total number of IP addresses, and assigned prefixes.
- Device Count Data—Provides information on whether an IP is used by 1 device, 10, or 10,000+ and whether sharing is concurrent or rotating over time. Useful for security, fraud prevention, and many other use cases.
- Hosted Domains API (aka Reverse IP API) — this API returns a full list of domains that are hosted on a single IP address. Domains are ordered based on host.io domain ranking.
- IP Geolocation Data — The API provides IP geolocation data that includes every IP’s continent, country, region, city, latitude and longitude coordinates, and postal code.
- IP Ranges Data—You provide us with a domain name, and our IP ranges API will return a full list of IP ranges operated or assigned to the provided domain.
- IP to Company Data — Provides data on the company that operates a network. Typically ISPs, hosting providers, governments, educational institutions, and large enterprises that register and operate their own IP blocks.
- Mobile Carrier Data — IP-to-carrier data allows the resolution of IP addresses to carriers. Our database provides information on every mobile IP’s carrier name, country code, and network code.
- Privacy Detection Data — The API provides VPN, Tor, open web proxy, hosting, and residential proxy detection. It makes it possible to analyze various methods used to mask internet traffic, including a connection via a hosting provider, which could potentially be used to tunnel traffic and mask the true IP address.
- Places Data — Our Places API identifies IP addresses associated with various points of interest, such as hotels, airports, stadiums, train stations, and more, with building-level precision.
- Residential Proxy Data — The residential proxy data detects IPs associated with proxy networks who route traffic through real ISP-assigned IPs, bypassing standard VPN and proxy detection entirely.
- WHOIS Data — Our WHOIS API provides properly formatted and up-to-date raw WHOIS records for every public IP address on the internet.
