Our reverse IP API allows customers access to a database that provides a full set of details for any domain name: IP address, ASN, total number of domains hosted on its IP range, and 25 most popular domains hosted on its IP range. These 25 domains are ordered based on their global Alexa traffic rank.

You can also use a domain’s IP range or ASN to return an API response containing its number of domains hosted, number of IPs operated, and a list of each IP address in operation. Our hosted domains API offers multiple endpoints that serve robust sets of data to our enterprise customers.

This data can be used to improve your website’s performance or experience in a number of ways, such as identifying web crawlers and scrapers. IP traffic that comes from data centers or server networks is often automated and programmatic. With IPinfo’s hosted domains API, our customers have 24/7 access to resolving any IP address to domain name.
