What is the difference between 1.2.3.* and 1.2.3.0/24? For me, it is
exactly the same. If you just want the ability to INPUT 1.2.3.*, just
write a small conversion routine in your favorite programming
language.

You don't even need to program the conversion, it is already done:

% netmask 1.2.3.0:1.2.3.255
        1.2.3.0/24
