Here, you will find links to my combined listings (in text format) for all known (to me) Chinese and Korean net blocks. I have provided two listings both containing the same sum data, but one lists contiguous ranges while the other is in Classless Inter-Domain Routing (CIDR) format

Please submit any additions or corrections to comments20140703@okean.com

Please feel free to cron the pulls of data from this site. If you do so, please make the interval no more frequent than once every 12 hours (once every 24 hours would be ideal). Site data is updated an average of 2-3 times a week, so pulling the data every hour or every few minutes consumes unnecessary amounts of my bandwidth. If you're pulling the data more frequently than every 12 hours, you can expect to be blocked without warning. If this happens, drop me an email, and you will be unblocked upon assurances that you have adjusted the interval to 12 hours or more.
