A much more important question: how will you be querying the data?
Partitioning is not a magic-bullet to performance, and when done
incorrectly it can end up hurting.
In this case, if the OP will be querying mostly on things that fit
within a class A, then partitioning on the first octet probably makes a
lot of sense. In fact, partitioning on the first two octets might make a
lot of sense, so long as there's very littly querying across partitions.
