Hi all,
Recently there have been discussions on blackholing 211.* on mailboxes.
Because I was sick and tired of the massive amount of spam (and
non-responsive network admins) I decided to blackhole them too. Because
211.* also has a piece of .au in it, simply listing 211.0.0.0/8 was not an
option for me.
I decided to put up a list, based on
ftp://ftp.apnic.net/pub/apnic/dbase/data/country-ipv4.lst
which lists the allocations per country in the form of
<countrycode>.rbl.cluecentral.net ie cn.rbl.cluecentral.net, and make it
pubically available.
You can check the list at http://www.cluecentral.net/rbl which is in the
tinydns-data format and of course use it for black/whitelisting purposes.
It is not yet updated automagically, I will write something for that soon.

Because of the incomplete stats published by APNIC, I have changed the way
data is collected. I am now using AS advertisements to generate the
zonefiles. More information about this is at

Thanks,
Fyi:
something I thought of a few weeks back that someone with lots
more time than I may want to do.
take these ip->country based mappings, create a
dns zone for "mx.example.com" (your domain) and create
different views that map the ip to different servers based on
source-country (eg: cn to cn.mx.example.com ip) and flag
messages based on that to set spam-level of detection.
etc..
