IP address conflicts with other systems on the network what does it mean to filter rogue IPs

Filter Rogue ipfunction deny_bad_ip ($kmLoginIP) {$bad _ip_arr = array (); $bad _ip_sql = "Select Ip,count (IP) num from Anlene_join_ User group by IP has num>100 "; Get Rogue ip$bad_ip_rs = mysql_query ($bad _ip_sql), while ($bad _ip_row = Mysql_fetch_assoc ($bad _ip_rs)) {$bad _ip_arr[] = $ bad_ip_row[' IP '];} if (In_array ($kmLoginIP, $bad _ip_arr)) {return true;} Else{return false;}}

The above describes the IP address and other systems on the network what is the meaning of filtering malicious IP, including the IP address and other systems on the network what is the meaning of conflict, I hope the PHP tutorial interested in a friend helpful.
