Internet sites to decide which ones to prevent your browser from visiting.
You can enable this function and add to the list of "banned" sites in two
ways:
• IP Addresses to block. Select this checkbox to tell the module to
identify dangerous Internet sites by using their Internet Protocol
(IP) addresses. To see or designate which addresses you want the
module to ban, click Configure to open the Banned IP Addresses
dialog box (Figure
Figure 4-32. Banned IP addresses dialog box
The Banned IP Addresses dialog box identifies which Internet
Protocol (IP) addresses you want the Internet Filter module to block
whenever you or someone else tries to connect to them.
By default, the list includes two sites that download hostile Java or
ActiveX objects to your machine as soon as you connect. You can
add other sites, then password-protect your settings to ensure that
users do not delete them.
Each address consists of four numeric groups of one to three digits
each, formatted in this manner:
The Internet Filter module can use this number to identify a specific
computer or network of computers on the Internet and prevent your
browser from connecting to it. Each group of numbers can range
between zero and 255. The first number series is the banned site's
domain address—the number you use to find it on the Internet—
and the second is a "subnet mask."
A subnet mask is a way to "remap" a range of computer addresses
within an internal network. The module lists a default subnet mask
of 255.255.255.255. In most circumstances, you will not need to
change this number, but if you know that a particular network node
at the site you visit is the source of danger, you might need to enter
a subnet mask to preserve your access to other machines at this site.
