I do not know the difference between Akamai's corporate blocks and
those used for caching. I also do not know the value of what you're
trying to accomplish.
But searching naively, there are at least 7291 Akamai IP blocks:

Those 7291 blocks can be summarized on bit boundaries down to 172 blocks:

Using this approach is a good start, but it cannot be complete. Some
caches are colocated with ISPs and use their IP space.
