This pattern matches the specified target items by combining multiple patterns with the '|' character, which acts as an OR operator in regex. The IP addresses are matched using '\b(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\b' to ensure they are not part of a larger number. The credit card numbers and product SKUs are matched using patterns specific to their formats. The URLs are matched by including the protocol and then any characters except whitespace. Phone numbers and special identifiers are matched using specific patterns to account for their unique formats.
