In short
A JSON file of CIDR prefixes an operator publishes for one crawler, usually with a creationTime field. An IETF draft (jafar) proposes a common format. 17 Index rows publish an IP list as JSON, the most common method, and 35 publish no method at all. Example: OpenAI's gptbot.json carried creationTime 2026-09-22 when read on 2026-11-04.
