Introduction How do you Block large number of IP address from your web application/server. Obviously that can easily be done in PHP or any programming language $ipList = []; // array list or from database if (in_array(getIP(), $ipList)) { // Log IP & Access information header("https://www.google.com.ng/search?q=fool"); // redirect exit(); // exit } Or Using htaccess order allow,deny deny from 123.45.6.7 deny from 012.34.5. # .... the list continues allow from all The issues Am trying to block a whole 100k plus individual IPs not subnets Am trying to avoid user getting to PHP before blocking such IP 100000+ is over 1.5MB and that is a lot if information to be loading in htaccess all the time Database of IP still growing ... and they would be nee to dynamically add more values To set bans in iptables for 100000+ is just ridiculous (Might Be wrong) Stupid Idea order allow,deny deny from database <-------- Not sure if this is possible allow from all Question Is it possible for htaccess to get the list from database (Redis,Crunchbase,Mongo, MySQL or even Sqlite) ... any Is there a visible solution to manage such kind of issue in production I know the best solution is Block the IPs at the firewall level is there any way to pragmatically add/remove IP to the firewall Finally My approach might be totally wrong ... all I want is a visible solution since spammers and botnets are on the rise ... Please this has nothing to do with DOS attack its a simple ... get lost response </
