because there are many different formats to different sources of listing of ip address to countries
the best thing would probably be to have a standard.
so here is going to be my standard file format for a database file.
the change will be in a future program
"ip2cntry.dat" will be the database that ip2cntry looks for

ip addresses will be in whole number format format
country will be two letters abbreviation and then long format
ex.
"33996344","33996351","GB","United Kingdom"
remarks in the file will start with a # so you can actually remark out a line
the first line to start with ## will identify the supplier of the list.
so the file many look like this:

## list provide by abc company
"33996344","33996351","GB","United Kingdom"
#"5033164868257567","US","United States"

#can be use to mark a line is not formated properly or that has trash in it.
notice how i messed up the 3rd line on purpose.

here are a couple of links to other information concerning this

sources of listing of ip addresses for countries
1. provided by ip.pl on http://Software77.net (A Webnet77.com Company)
download here
http://software77.net/cgi-bin/ip-cou...tion=downloadZ

2. provide by MaxMind
http://www.maxmind.com/app/geoip_country
download here

3. some general info
http://people.netfilter.org/
http://people.netfilter.org/~peejix/geoip/howto/geoip-HOWTO-2.html#ss2.1

i cannot confirm the accuracy of these listing.
maybe a cross check later but do not count on it

program to convert geoip csv database
they have another database i cannot and do not want to read.
the csv file i down loaded had many errors in the format
http://www.maxmind.com/download/geoi...CountryCSV.zip

get geoipcountrycsv.zip
this program creates a ip2cntry.csv file on purpose, not the ip2cntry.dat file which my program will use.
therefor your good file ip2cntry.dat will not be damaged until you verified ip2cntry.csv then after copied it to ip2cntry.dat

I'm pretty sure Yahoo or Google or Amazon have a web service to do this down to the city level. Would be a whole lot simpler to use a web service vs. maintaining a csv "database".

**Paul Purvis** · 6 Jun 2008, 08:17 PM

i keep logs of all my router history and want to know what is going on.
today after creating some reports, i feel like going to the barn with a lot of people not in the USA.
the biggest problem comes from where people are in countries where you cannot prosecute people.
In Lousiana, USA, and probably most other states, it is a crime to just to try to access intellectual information, you do not even have to succeed.
also i will be downloading emails with a pop account with a build in program and if the ip address is there, i can handle it.
after yahoo advertised my competitors on my website with them, i will try to live without yahoo and i do not need google knowing anything about web addresses that comes to my site either.
also the country ip addesses data will most likely be shared
this kind of information should be available freely from a usa gov site and i know who to talk to.

thanks for the heads up

a newer version of the ip2cntry program in the source code section has been updated.
the program now reads the standard ip country database i mentioned above.
also the program has been speed up tremendously
i sorted the country database in memory and installed a loosely written binary search routine to locate the records in the database stored in an array.

i had a little trouble in searching the ip country database array because of the ranges, so i just had the search routine get close to where the range might be then i read through the array sequentially for a match until either a match was made in the range or the ip address searched for was higher than the last range read. it is not very clean but it is very fast.

**Paul Purvis** · 8 Jun 2008, 03:43 PM

i posted a version of the ip2cntry program in DLL executable format in the source code section.
the program adds much more functionality, you can also specific different databases as long as they are in the standard format the program is using.
this newer version should be much more useful in many different ways.

a though occurred to me in another way of using this program.
if you have any program where you want to limit the access to that program, you can screen for specific ip address or ranges of address easily by having a custom list of ip addresses.
also if you wanted a program to direct a ip address or certain of ip addresses to a particular website or some other kind of direction, you can use the text that would normally be used for the 2 character country and the longer country name for other purposes of your creation.
but i would length the descriptions of at least the full name of the country. it should be very easy to maintain the database or simply add more fields to the database.

**Paul Purvis** · 9 Jun 2008, 04:36 AM

i did a simple cross check of ip listing from maxmind and webnet77.
the results are in 4 files
compare maxmind to webnet77 listing
maxminda.lst
maxmindb.lst
compare webnet77 to maxmind listing
webnet77a.lst
webnet77b.lst

files at
pdptemp.dyndns.org/zipcode

i have not taken much time to analyze the reports
but just a quick look at it and a lot of the differences are countries near one another.
there is two list for each run
one of the listing is where there was a match
the other one is where there was no match on a ip address

in both listing i just picked up the first and last numbers in the range in the list and compared to see if the ip address was in the the other file and with what country
paul
without much review, i would think maxmind(geoip) should be more accruate.
although country names maybe different, i just compared the two character abbreviation of country names.
