If you have measured some suspected IP address don't worry you can restrict those IP addresses in PHP. Those IP will not be able to access you website.
Here I have created a text file where all the block ips has been written. And I also have created blocked IPs array. I will get the client IP and then will check the blocked list of IPs if user IP exist in the blocked IPs array then will show the message on website.

<?php
if ( !file_exists('blocked_ips.txt') ) {
$blockIPS = array(
'127.0.0.1',
'192.168.21.100',
'85.78.17.90',
'192.168.1.176'
);
} else {
$blockIPS = file('blocked_ips.txt');
}
// you also can get blocked ip array from your database
// read user ip adress:
$ip = isset($_SERVER['REMOTE_ADDR']) ? trim($_SERVER['REMOTE_ADDR']) : '';
// search current IP in $blockIPS array
if ( (in_array($ip, $blockIPS))!== FALSE ) {
echo 'Your IP adress ('.$ip.') was blocked!';
exit;
}
?>
