Don't Use This for the Internets

[supertylerc]

This probably goes without saying, but maybe add a note to not use this with the full Internet table. I was curious about performance and did it anyway. :D

Thought I had that in there actually. :)

I'll make a note of it but might be a good idea to have it as a flag to ignore public ASNs when parsing. (With optional exceptions for owned ASNs)
