--[=[ Functions are not "local", so other modules can require this module and call them directly. We return an object with 3 small stub functions to call the real ones so that the functions can be called from templates also. Only [[dotted decimal]] notation for IPv4 supported. Does not support dotted hexadecimal, dotted octal, or single-number formats (see [[IPv4#Address_representations]]).
