RegEx Pattern for FQDN Address Object

When you try to create an FQDN Address object, you can't use wildcards.

NGFW

• Wildcards or regex patterns cannot be used to form a valid FQDN
• The validation of FQDN object is performed using the RegEx pattern ^([a-zA-Z0-9._-])+$ by the system to determine if a given hostname uses valid characters.
• Where ^ specifies start of a string, and $ specifies the end of a string, and + indicates one or more strings in the Round Brackets.
• [a-zA-Z0-9._-] indicates any character specified in the Square Brackets, which does not include any other special characters other than  '.' , '_' , '-' .
