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,
