Overview: Enabling IP address intelligence
An IP intelligence database is a list of IP addresses with questionable
reputations. IP addresses gain a questionable reputation and are added
to the database as a result of having performed exploits or attacks, or
these addresses might represent proxy servers, scanners, or systems that
have been infected. You can prevent system attacks by excluding traffic
from malicious IP addresses. The IP Intelligence database is maintained
online by a third party.

The BIG-IP system can connect to an IP intelligence database, download
the contents, and automatically keep the database up to date. You use
iRules to instruct the system on how to use IP address intelligence
information. For example, iRules can instruct the system to verify the
reputation of and log the originating IP address of all requests.

You can also use the IP address intelligence information within security
policies in the Application Security Manager to log or block requests
from IP addresses with questionable reputations.
