IPV4 and IPV6 IP to Country Database: to search online as well as download.
Database License: DONATIONWARE
Previously, This DB was licensed  differently (GPL V3), which restricted many commercial developers from using it at all.

Now, it's "donationware". Problem is, many are using it in commercial products, benefiting financially without giving a thought to the source - this database.

It's simple: we cannot offer tens of thousands of downloads per day without assistance. Please help us.... the PayPal link is right above.

Many thanks!

About
This Database and website is operated as a free Web Service maintained by Webnet77 and updated daily. It represents the over 4 billion IPV4 numbers as well as the virtually inexhaustible IPV6 range (3.4e+38).

We have been running this database as a free community service since 2004 and will continue to do so for as long as funds permit. We do ask that you consider making a donation as our operating cost for this site have increased substantially over time - As more and more developers build our database into end-user applications, downloads increase non-linearly.

For example, all it takes is some new Ubuntu distro or Wordpress plugin to be released that uses this database and we suddenly have an extra 10,000 downloads per day. Wordpress or Mambo don't get updated daily but this database does, so in many cases, people download it daily hence the number of daily downloads increases disproportionately as application usage increases.

In the past 3 hours the database has been downloaded 30,803 times.
 
CONTRIBUTIONS/DOWNLOADS
Contributions by various members of community. Here you will find scripts written in languages like Perl, PHP, Java, awk as well as bash. The applications vary from firewall applications to bind acl's as well as browser based country lookup scripts you can use on your website. Most scripts are licensed under the public domain, GPL or creative commons licenses.

How often should you download this database?
If you use our IP to country Database in your applications you should get an updated copy from time to time. Depending on your application, probably once a month should be fine. We have observed up to 50 row changes from a single registry in a one day on busy days. Some days there are far fewer.

This may sound like a lot or a little depending on how you look at it. Mostly it will not affect you and sometimes it can be significant. For example, a Registry may allocate a block of IP numbers for a specific event - like an international trade show. These IP numbers may be valid for a few weeks only and then revert back to the registry when the show is over. Unless your application has an interest in the trade show event, the assignment/revocation of these IP numbers will have little impact on you or your application.
