python-whois
python-whois python-whois is the flexible Python lib for querying WHOIS servers, parsing responses for domain/IP ownership with support for RDAP transitions and custom timeouts for recon workflows. Import and call whois.whois('example.com') for dict outputs, scripting bulk lookups for OSINT chains. Open-source from r-degges, it's the query quester for pentesters templating domain intel gathering.

whois whois is the GNU CLI client for RDAP/WHOIS queries on domains and IPs, extracting registrant details and netblocks with verbose parsing for footprinting. Compile from C source, run on targets with -h for headers, piping to jq for structured data. Open-source from GNU, it's the registry reader for recon rangers tracing assets to owners.

jwhois jwhois is the enhanced WHOIS client with caching and multi-protocol support, querying gTLDs or RIPE for parsed outputs in recon phases. Configure .jwhoisrc for servers, run CLI on domains for detailed fields like abuse contacts. Open-source from GNU, it's the query enhancer for OSINT pros customizing lookups.

rdap-client rdap-client is the modern RDAP querier for domain/IP WHOIS, fetching JSON-structured data from registries with filters for structured recon outputs. Run its Go binary with -type domain, exporting for scripts. Open-source from community, it's the RDAP resolver for pentesters templating future-proof lookups.

whois-parser whois-parser is the Node.js lib for normalizing WHOIS responses into JSON, stripping noise for consistent fields like creation dates in automated intel gathering. Pipe queries through it in scripts, handling variations from registrars. Open-source from Haxx, it's the parser purifier for devs cleaning WHOIS data.
