That search is for the IP, not the UA. However, besides my own post, I just see people attesting they block Chinanet. Well so do I... and all of China for that matter. I already knew I blocked it - LOL.
My OP was just to document the UA. I know where it comes from. At least I know where the WHOIS says it comes from.
Point is, China has thousands of server farms, colos, dedi servers, etc just like the rest of the world, except they all get funneled into several China ISPs similar to the way parts of Russia are. Theoretically, IPv6 will help us to identify in a more specific way, but that remains to be seen. If all goes as planned, I will probably take down my wide blocks and be more surgical.
Funny you should say that. I wasted a lot of time this evening trying to make sense of the monstrosity that is 38. The blasted thing's got humans and robots so closely intertwined there's no separating them, and random bits of Canada subleasing from what should be a US range, and the whole thing is chopped into such teeny little pieces you might as well be in APNIC, and...
Oh, and UAs with escaped quotation marks drive me bonkers because my log-wrangling function can't deal with them so the whole thing gets left out in the cold.
