### How did you test IP company lookup APIs?

On 5 November 2026, we sent 17 providers the same list of 20 IP addresses.

The Accuracy score on IP company lookup APIs: This score shows how much of an IP address's owner record a provider's call gets right, out of 100. We send each provider the IP address. We score four parts: the ASN, the owner's name, the owner's domain and the network range. We check each part against the registries: RIPEstat's routing data, the address's record at the regional registry, and PeeringDB. We never check an answer against another provider's answer. For each address, we divide the right parts in the answer by the parts the registries list. We average the scores over all addresses. Each address counts the same. An address scores 0 when the answer names no owner. Some providers say they may answer from a stored copy of their data. We check those answers against the same registry records. We lower the score when we test the call on fewer IP addresses than the benchmark has.
