A pure Ruby WHOIS client library that performs WHOIS lookups for domains, TLDs, IPv4, and IPv6 addresses, with intelligent server guessing and extensible custom server definitions. Parsing of WHOIS responses is provided by the companion whois-parser gem, and a CLI is included for console queries.

Use cases

• look up whois record for a domain name in ruby
• query whois server for an ip address
• check domain registration availability programmatically
• parse whois response into structured data
• find expiration date of a domain
• run whois queries from the command line
• define custom whois servers for new tlds

When to choose

• you need WHOIS lookups in a Ruby or JRuby application with zero external dependencies
• you want a mature, production-tested library (in use since 2009) with semantic versioning
• you need extensible WHOIS server definitions and structured parsing via whois-parser

When to avoid

• you need WHOIS in a non-Ruby language
• you need RDAP instead of legacy WHOIS protocol
• you need bulk high-rate lookups, which may hit registrar rate limits
