CIRCL hashlookup and BGP Ranking

hashlookup combines the NSRL Reference Data Set with operating-system and package-repository sources; its status response reported 6,532,066,294 keys and NSRL version 2023.09.2 when checked. BGP Ranking covers autonomous systems observed through CIRCL's external security data and exposes current and historical ranking endpoints. hashlookup has no service-level commitment; neither service states a rate limit or promised refresh schedule, although the optional hashlookup Bloom filter updates monthly.

Licence note
CIRCL licenses the open data described on its open-data page under CC-BY-4.0 unless a resource says otherwise, and the hashlookup OpenAPI metadata labels that API CC-BY without a version. hashlookup responses incorporate named upstream datasets, so preserve source and provenance fields and check upstream terms for redistribution.
