Some hosts need to be changed to be compatible with this, they are in the same archive as this file.

INSTRUCTIONS:
	Copy this file to the rapidleech root
	Create the file /logfile/mip_iplist.txt
	Add 1 ip per line on /logfile/mip_iplist.txt
	Check php has read access to /logfile/mip_iplist.txt
	Apply the modifications
