Compiled GeoIP Database

Download

Several years back I was programming a network utility that needs an index relating IP network numbers to network names and identities, for class A, B and C networks, I found this list compiled from the Internet.

I know that you can always use whois, or some online website to achieve the same thing. MaxMind even has a collection of GeoIP APIs that can be used. There are even companies provided IP to city/region/country mapping database. However the list here is more details as it provides the identities as well.

The list is extracted from the whois database at the Internic. As of December 22, 1997, control of IP network allocation has passed to Arin (American Register of Internet Networks). There are similar organisations for European (www.ripe.net) and Asian-Pacific (www.apnic.net) networks.

As an example, see below
