I personally think just storing the autonomous system the IP originates from and never writing the IPs to disk at all would be advisable if the goal is purely which ISPs are delivering how many bytes to end users. Another benefit is the AS to IP mapping database is small enough to fit in memory without issue.

That's probably insufficient for the usecase. A single AS can advertise many different routes for different IP blocks that have dramatic geographic differences.
