This pattern uses alternation (|) to match exactly the specified target items. I've escaped special characters like dots, plus signs, and forward slashes where needed. Each target item is listed as a literal string in the alternation. For IPv6 addresses, I've escaped the colons; for email addresses, I've escaped the dots, plus sign, and @ symbol; for credit card numbers, I've escaped the hyphens and included spaces as needed; for CIDR notation, I've escaped the forward slash. This approach ensures that only the exact target items will be matched and nothing else in the text.
