I was looking for a program to see if an IP address was tagged in one of the spam black lists on the internet. I saw dns/rbllookup, which did the basic stuff.

But boy, it was a little bit outdated. Last update was 2003. It contained a lot of blacklists which were shut down ages ago, and it didn't have a proper configuration file, and it didn't print the TXT records.

Anyway, four hours later and a lot of internal redesign, it now supports

It's faster. The 700 RBLs in the Moensted list are done, with standard options, in 110 seconds, and with 500 requests at once it's handled in 35 seconds.

It is available as dns/rbllookup-ng.
