can someone explain, why the two packages
-  GeoIP
-  geoipupdate
are needed when installing the bind-utils package?
The bind-utils package requires 'libGeoIP.so.1()(64bit)', which is
provided by the GeoIP package.  The GeoIP package requires
'geoipupdate', which is provided by the geoipupdate package.

% rpm -q --requires bind-utils|grep GeoIP
libGeoIP.so.1()(64bit)
% rpm -q --requires GeoIP | grep geoipupdate
geoipupdate

GeoIP provides a C library and a lookup tool to look up countries from
an IP address.  The bind-utils executables are all linked against
libGeoIP.so.1, so I assume they use some functionality from that
library.

/usr/bin/geoipupdate is a tool to update the data files in the GeoIP
package.

Yes, then the interesting question, how can I make use of these GeoIP-features when
doing these e.g.

nslookup    200:470:17:55::1
nslookup    222.10.10.1
nslookup   www.centos.org
host     www.centos.org

Thanks,
Walter
