It handles the bootstrapping logic (determining which RDAP service to query for a given resource) and parses RDAP JSON responses into flat dictionaries, so you don't have to implement HTTP routing and JSON extraction yourself. The library supports lookups for autonomous system numbers (ASNs), domain registrations, IPv4/IPv6 addresses and CIDR blocks, and entity handles across regional internet registries (ARIN, RIPE, APNIC, LACNIC, AFRINIC).\n\nIt offers both synchronous and asynchronous query methods, with options to retrieve raw RDAP JSON, follow related RDAP endpoints for richer domain data, and work around weak SSL implementations on some registry servers. The library is pure Python with minimal dependencies and requires Python 3.10 or later.","worth_installing":"Yes, if you need to query RDAP services for internet resource data. The library is actively maintained, has low install friction, and handles the bootstrapping and parsing complexity that would otherwise require manual HTTP and JSON work. Verify the license terms in the repository first, since the package metadata does not record them.
