Unfortunately, we have a very coarse level of specifying a subnet mask 
for a range of IP addresses.  If you are using one of the old, class 
domains, you can use an astrisk to specify a subnet.  E.g., a class-B 
subnet can be specified as "127.99.*.*"

We've been in a classless net (isn't it wonderful?) for almost a decade 
now, so the 'correct' way to specify a subnet would allow us to break on 
any mask.  ("127.99.0.0/16" in the previous example, or even at a finer 
grain of specificity:  "127.99.232/22")

I think I send this in as an enhancement request every year, but it 
isn't a high enough priority.  (It is also hard to explain the classless 
network address system to those who like the simplicity of the class
address blocks.)
