I just wanted to say a quick thank you for all the input. I did some experimenting, and for my use case I ended up with an sqlite3 database that I built myself from the csv tables.

It took way too long to ingest the data every time I needed it, and I have sqlinte3 on the small box that I want to run this. Using an external call takes to long, and could potentially rate limit. I put a primary index using the first octet, and that made the search way faster.
