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 50 people, and grown our data offerings to include geolocation, IP to company, carrier detection, and VPN detection. Our customers include T-Mobile, Google, DataDog, DemandBase, and many more.
