How do I ban an IP Address via .htaccess?
If someone is trying to hack your website or you want to block their IP Address, you can add this line to your .htaccess file.
order allow,deny
deny from IP-ADDRESS
allow from all
Replace "IP-ADDRESS" with the IP Address you want to block.
Website packages like WordPress have more advanced facilities available to add (Wordfence in the case of WordPress) to provide these facilities.
