To follow up on the previous post, the IP Ranges in the ip-to-country.csv file are in numeric value. So instead of 10.21.232.22 or something like that, the range is indicated by integers.

An IP address can be compared to these range-boundaries by first turning it into an integer itself. That is done by the following function – for IP Address = w.x.y.z.:

IP Integer = w*256*256*256 + x*256*256 + y*256 + z

So for example the address “209.207.224.40″ should be converted to 209*256*256*256 + 207*256*256 + 224*256 + 40 = 3520061480. That number can be compared to the IP ranges in the file.

Along with my search for WordPress plugins that cater for statistics, I found a very interesting site, with an IP-to-Country plugin for WordPress. See http://ip-to-country.webhosting.info/node/view/21 for an introduction to a WebService IP-to-Country. The same site allows download of a CSV file that contains IP-ranges and their translation to Country! The IP-to-Country Handbook » General information about IP-to-Country

Here the URL’s that didn’t show up in my last post:

AWstats: http://awstats.sourceforge.net/cgi-bin/awstats.pl
Ip Adresses via AWstats: http://awstats.sourceforge.net/cgi-bin/awstats.pl?framename=mainright&output=allhosts

Etc.

Ip adresses can be tracked by most analyzers, what the use to combine them with arpa lists of contries is “reverse DNS lookup”. If i am not mistaken, this can be done via Webalizer. The problem with this is that an extra deamon process is needed and therefor an extra entry for hackers has to be protected against unwanted entries.

There are some very usefull and powerfull statistic programs. For instance one, an opensource, tool
is
AWStats It gives you not only a lot of usefull info about ip numbers en countries,
but also information about exit codes. These exit codes are interesting to see if your site is working properly PLUS if there are people who try to hack there way in… AWStats is written in perl, but there are alternatives.

An other tool is Webalizer.
A sample report can be seen at http://www.webalizer.com/sample/usage_199905.html
