iptables rule sanity check?

why would:
Code:
 iptables -A INPUT -s 180.0.0.0/8 -j DROP

along with /etc/hosts.deny rule of
Code:
 ALL: 180.0.0.0/8

not stop traffic to/from 180.x.x.x, which I still see by running iftop? Or could iftop just be showing an artifact and is there a better way to monitor connections real-time?

SYNOPSIS
resource imagerotate (resource $image, float $angle, int $bgd_color, [int $ignore_transparent]) DESCRIPTION
Rotates the $image image using the given $angle in degrees. The center of rotation is the center of the image, and the rotated image may have different dimensions than the original image. PARAMETERS
o $ image -An image resource, returned by one of the image creation functions, such as imagecreatetruecolor(3). o $angle - Rotation angle, in degrees. The rotation angle is interpreted as the number of degrees to rotate the image anticlockwise. o $bgd_color - Specifies the color of the uncovered zone after the rotation o $ignore_transparent - If set and non-zero, transparent colors are ignored (otherwise kept). RETURN VALUES
Returns an image resource for the rotated image, or FALSE on failure. CHANGELOG
