IPinfo.io

IPinfo is a leading provider of IP address data. Our API handles over 100 billion requests a month, and we also license our data for use in many products and services you might have used. We started as a side project back in 2013, offering a free geolocation API, and we've since bootstrapped ourselves to a profitable business with a global team of over 40 people. We've grown our data offerings to include geolocation, IP to company, carrier detection, VPN detection, ASN details, hosted domains, abuse contacts, and Whois data. Our customers include T-Mobile, TransUnion, DataDog, DemandBase, Clearbit, Nike, Plesk and many more. We provide accurate, reliable data via easy-to-use APIs (backed by Google Cloud infrastructure) and database downloads (CSV, MMDB, JSON). Our infrastructure handles billions of daily queries with 99.99% uptime, and data is secured via 256-bit SSL.
