Wildcard Mask Rule matches a quad-dotted textual IPv4 address representation to a single specified text entry supporting wildcard character replacements.

Two wildcard characters are recognized:

• * (asterisk): stands for any number of characters or no characters at all
• ? (question mark): stands for a single mandatory character

Character in the LANProtector context stands for both . (dot) and for any number in the IPv4 address quad-dotted notation.

Examples:

• Text *: matches any address
• Text 192.168.10.*: matches addresses in the range from 192.168.10.0 to 192.168.10.255
• Text 10.10.1?.5?: matches addresses in the range from 10.10.10.50 to 10.10.19.59
