ip deny manager in cpanel
i tried banning few ips from accessing to my website, however it didn't work out. they are still able to access to my website.for example his ip is 123.123.123.123
so should i ban 123.123.123.123 exactly or it has to be 123.123.123.* to ban that ip?
or is there any alternative way to ban an ip? i was told that we could edit .htaccess in public_html.
please assist me on how to do so!
