The pattern uses alternation to match different types of data:
1. IPv4: Matches the three valid IP addresses with precise octet ranges
2. IPv6: Three patterns for the different IPv6 formats (full, compressed, and ::1)
3. Card numbers: Matches the specific formats with either hyphens, spaces, or just digits
4. Dates: Matches the three valid date formats (YYYY-MM-DD, DD/MM/YYYY, YYYY.MM.DD)
5. Product codes: Matches the valid product codes with exact format
6. URLs: Matches the two valid URLs with their exact query parameters

Each part is carefully constructed to match only the valid items and avoid matching invalid entries.
