Hello,

seeing that 6991 is up for a refresh I wonder if this would be the time 
to suggest the addition of a type for address-and-prefix-length, for 
example like 192.0.2.1/24?

I find that it's the most natural way express the address and 
prefix-length to configure on an interface or for some other use. We 
currently have an ip-prefix type which allows CIDR style prefixes but 
since all bits to the right of the mask is to be 0 it is only possible 
to use for describing the IP prefix / network address itself - not the 
address of a host in that network.

I actually wish the interface-ip modules would have used a combined leaf 
for these settings rather than the dual-leaf approach it currently has, 
but I suppose that ship has sailed :/

Regardless, can we add such a type? Is this the document and time to do 
it? :)

Kind regard,
    Kristian.
