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]]).
