currently :

The reputation file lists a reputation score for hosts in the categories. It's a simple CSV file:

    <ip>,<cat>,<score>

The IP is an IPv4 address in the quad-dotted notation. The category is the number as defined in the categories file and the value is a number between 1 and 127. 0 means no data.

Example:

1.2.3.4,1,101
1.1.1.1,6,88

I think it would be helpful if whole network ranges can be included:
11.11.11.0/24,6,88

Thanks
