isn't a class C the same as /24?
I used this table:
CIDR Block
Prefix # Equivalent Class C # of Host Addresses
/27 1/8th of a Class C 32 hosts
/26 1/4th of a Class C 64 hosts
/25 1/2 of a Class C 128 hosts
/24 1 Class C 256 hosts
...
(maybe there's another definition of a class c
i'm not common with...)
