Extract blocked IPs from the database?
If you want to extract blocked IPs from the database so that you can process them with other software you can do a MySQL query like this
Please note that MySQL >= 5.6 is required.
SELECT INET6_NTOA(IP) FROM wp_wfBlocks
If you want to output the results to a file, you can do that with this code
SELECT INET6_NTOA(IP) FROM wp_wfBlocks INTO OUTFILE '/writable_directory_by_mysql/blocked_IPs.csv' LINES TERMINATED BY '\n';
