I have a spreadsheet that has a column with IP addresses. I need to populate another column automaticly with the country that IP is registered to.

Then do a vlookup on your ip using a formula like
=VLOOKUP(--SUBSTITUTE(A1,".",""),'ip-to-country.csv'!\$A\$1:\$E\$111799,5)

This will only work in excel 07 and above since excel 03 is limited at 65,536 rows, and the csv file has 111,799.

Here is an example, including that database. You can have IPs with . or not.

I have worked on such project before using programming language but did not finish it.
My finding was: there is range of numbers, every range represents a country, then you calculate any IP using an equation (math equation) to arrive to a particular number then you match the result number to the ranges to get the country.

Ok, this database is not correct.

i have found another solution:

="http://api.hostip.info/country.php?ip=" & A2

It is possible to get a result in the excel file?  because this create a link and not show the result in the file.

thanks

cawasaki,

(1) nutsch's formula for converting dotted decimal addresses to pure decimal was incorrect. Please try the attached instead. (To save on the upload, I deleted all the rows in "ip-to-country" - just copy and paste the rows from the original beneath the header.)

(2) You mentioned that the database was incorrect. Was this because of the conversion error or did you find mistakes in the data? There are certainly gaps in it (e.g. 192.168.0.0 to 192.168.255.255 is one of the Private Address Spaces).

Thanks,
Brian.
