> Wouldn't a columnar store be 25 512MB arrays?

Hm I guess you're right - I'm misusing the term. And yeah! Will experiment with it; what's neat is that it's not that much code to mess around with these basic notions...

Re: 224 << 24 - you're right; so many unusable actual addresses. It's just kind of neat to actually map out whole ipv4 space to memory. But yes lots of it unneeded, I'll see if I can add minimum-computation-possible mapping translation so that everything still stays ~kind of O(1).

Thank you for your comments! :)

edit P.S. 25 x 512MiB arrays - actually thank you, I thought of doing sth like that at first, but now forget why didn't start experimenting with that sort-of-actual-columnar-store from the beginning.. anyway, nice to quickly mess around with multiple base data layouts (I'll try that one next I think), would recommend anyone wanting to attain base knowledge on e.g. data layouts for data analysis...
