Comment(by gsathya):

 Replying to [comment:2 karsten]:
 > Hmm.  How about a third approach: write a library that a) reads
 unmodified database files to memory, maybe together with a mapping file
 containing dates when these files became valid, and b) resolves IP
 addresses and dates to country codes or ASes.  We wouldn't want to
 memorize the full file contents, but only the relevant information for
 looking up an IP address and date.  But we can still wonder about a
 compact file format for that later on.

 This means we'll have to store multiple GeoIP database files. Is this a
 good idea? wouldn't it be better to have a single file?
