As far as I understood from the instructions on the link
https://ircbl.org/about the correct values to check would in your case be will be like this:
<dnsbl name="ircbl"
type="record"
domain="rbl.ircbl.org"
action="GLINE"
reason="[K-banned:[exp/comp] Compromised host on this IP. See http://ircbl.org/lookup?ip=%ip% for more information."
duration="1d"
records="21"
>
This is the same as if you manually check each proxy address using the command. For example, such an IP address "
103.241.227.110" is written in reverse order:
/dns 110.227.241.103.rbl.ircbl.org
If an answer is received in the form "
127.0.0.21", this means that the IP address was found in the database lists of this DNSBL server as a (bad) address that is being used by attackers.
For those using my script, which is presented in the post
#Post268254 you need to add a line inside the alias "
proxyscanner_list":
.hadd -m ps-dnsbl rbl.ircbl.org 21
P.S. This way will require additional on the working capacity rechecking to catch user connections through proxy addresses. You can report your observations here.
