Understood Luciano, is there a list of supported DNS blocklists then? There is a link on the page you supplied however the vast majority of those do not work with this sensor.
Also when checking the blocklist manually I can seen Spamhaus does list 127.0.0.2 as would be expected:
127.0.0.2 is listed in the SBL, in the following records:
127.0.0.2 is listed in the PBL, in the following records:
127.0.0.2 is listed in the XBL, because it appears in:
Are there any details on how this .exe is actually checking the BLs? It seems like the issue might be with the lookup rather than the lists themselves. For example the above shows that 127.0.0.2 is in the XBL/CBL for Spamhaus.
Zen.spamhaus.org lookups include all DNS lists (Specifically including the XBL) however if I use the exe against this server, as before I get:
|IPonDNSBL.exe -ip=X.X.X.X -bl=zen.spamhaus.org|
Error checking zen.spamhaus.org, it contains no entry for 127.0.0.2
