whoisclient

Querying and parsing Java whois client

Rationale

Based on whoisclient by (https://github.com/minorg/whoisclient) but totally rewritten.

Features and changes

• support whois servers for the most of modern domains
• support hierarchic lookup in parent whois servers
• uses simple key-value map for data access. Supports multiple values for key
• search value by several keys in single call
• get rid of huge regexps, and reflections

TODO

• use predefined list of whois servers in order to stop abusing whois.iana.org each time
