## Roadmap Item

- Version: 2.3.0
- Feature: WHOIS Integration

## Implementation Tasks

- [ ] Research WHOIS protocol implementation using built-in Node.js modules
- [ ] Define WHOIS data interface/types
- [ ] Create mapping of TLDs to WHOIS servers
- [ ] Implement `getWhoisData(domain)` function
- [ ] Create parsers for different WHOIS response formats
- [ ] Implement caching to respect rate limits
- [ ] Extend `IDomainInfo` interface to include WHOIS data
- [ ] Update `fetchDomainInfo` to include WHOIS data
- [ ] Add comprehensive test cases
- [ ] Update documentation and examples

## Technical Requirements

1. Use only built-in Node.js modules where possible to minimize dependencies
2. Handle different WHOIS server formats gracefully
3. Extract at minimum:
   - Registration date
   - Expiration date
   - Registrar information
   - Domain status codes
4. Handle privacy-protected domains appropriately
5. Implement appropriate error handling
6. Add caching mechanism to prevent excessive queries

## Acceptance Criteria

- [ ] WHOIS data is successfully fetched for common TLDs (.com, .org, .net, etc.)
- [ ] Response parsing correctly extracts key information
- [ ] Error handling gracefully manages unavailable WHOIS servers
- [ ] Rate limiting prevents excessive queries
- [ ] Tests verify functionality across different domain types
- [ ] Documentation clearly explains new functionality
- [ ] Examples demonstrate WHOIS data usage

## Dependencies

- No external dependencies needed
