This plugin checks if the client is listed in RBLs (Real-time Blackhole Lists).
|
|
These are lists of IP addresses misbehaving. There are many RBLs, some are more
|
|
aggressive than others. More information at http://en.wikipedia.org/wiki/DNSBL
|
|
|
|
This filter will result in one DNS request for every blocklist that you have
|
|
configured. This might be problematic for sites under heavy load, although this
|
|
plugin has been used on high-traffic sites without any problem. One DNS
|
|
request takes a few miliseconds to complete, after all.
