BL-Monitor PRO Reports the Filtering Overlap Between DNSBL
Servers
|
Go to BL-Monitor PRO Main |
|
|
To get maximum filtering effectiveness, DNS Blacklist servers must be
chosen to minimize the
number of IP addresses in common.
The BL-Monitor PRO IP overlap report helps to avoid wasting resources by using DNS Blacklist servers with similar blacklist
databases.
|
BL-Monitor PRO analyzes each pair of DNSBL servers to
search for common IP addresses. The results are reported in a
clear, easily readable table format.

Sample BL-Monitor PRO Overlap Report |

The sample Overlap
Report demonstrates how quick and simple it is to determine
overlapping DNS Blacklist servers.
|
Here it is shown
that blacklist
servers "BL 1"
and "BL 3" have 48% of their IP addresses in common.
In this situation, choose either one or the other but not both
together. |
