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.
