This blog post illustrates why ipapi.is surpasses ipinfo.io in terms of company and ASN data accuracy. Several samples of IP addresses and ASNs are looked up on both API providers and the results are compared. It turns out that ipinfo.io often fails to find the correct organization name and organization type, which has a significant impact on the accuracy of the API.

Since the establishment of ipapi.is in late 2022, the API has grown to become a new serious contender in the IP API field. One of the oldest and most reputable IP API services is ipinfo.io. This blog post discusses the question whether ipapi.is is a viable alternative to ipinfo.io and if ipapi.is might even the better option for some organizations in the cybersecurity field, since the pricing of ipapi.is is much lower, while the data accuracy is similar if not better.

This blog article explores whether using Reverse DNS lookups across the entire IPv4 address space can enrich IP API data. The idea is to utilize Reverse DNS data to enhance IP Geolocation accuracy and to determine the connection type of IP addresses.

WHOIS data is the most crucial data source for ipapi.is, as it allows the derivation of the organization that owns a specific IP address. Additionally, WHOIS records can be used to derive useful metadata such as domain names, email addresses, and geolocation intelligence.

In this blog post, we describe in depth how the IP ranges of a substantial part of the hosting providers on the Internet can be detected. Knowing whether an IP address belongs to a hosting provider or not helps in making better IT security decisions.
