For instance, with the example above, if you input, e.g., ""bletch"", you get the error message ""Enter a valid IPv4 or IPv6 address"", even though IPv6 addresses are not allowed. (However, if you input, e.g., ""::1"", you get the accurate message ""Enter a valid IPv4 address"".) It seems like GenericIPAddressField doesn't pass its protocol in its formfield() method, so the GenericIPAddressField form field first uses a more general validation rule than the GenericIPAddressField model field.
