[NTLUG:Discuss] All non-US IP list?

[. Daniel]

It didn't work for me the first time, but it worked when I did a page 
reload.  I read on their page that they need a secondary DNS server... that 
probably has something to do with it.

Okay so now I just need to get these IPs imported into greylisting and so I 
need to process the list somehow.  Now where did I put that Perl coding 
expert?  I had him around here somewhere.... 

In any case, the data I seek is here:

http://www.blackholes.us/zones/countries/countries.rbl

Now I just need a way to parse it... Perl is such a powerful language... 
it's just so hard to look at!  *WAY* back in the day, I used to write C 
code... actually 6809 assembler, BASIC of many flavors, Basic09 and C.  
Never got into C++ or anything object oriented... that broke my mind.
