Implicitly in 1518, for example:
---------8<----------------------8<----------------------8<------------
For the purposes of this paper, an IP prefix is an IP address and  some indication of the leftmost contiguous
significantbits within  this address. 
 
---------8<----------------------8<----------------------8<------------

As I already explained, the use of variable-length masks implies that
they have to be explicitly stated. This was not neccessary in classed
networks, as the MSB's encoded the class (mask).

Because a cast to network is a cast to CIDR - casting to the same type
obviously won't change a thing.

As a matter of fact, it is the side effect of the current
implementations shortcomings - we have common code for INET and CIDR,
otherwise, network would not have to be a valid operator for CIDR.

Huh? The only *network* I see in there IS in /bits notation.
