I use this for a geolocated DNS system and it works well.  I have actually manually referenced this to find where a 
specific block is from. 

I found that list to be out-of-date and slow to change (when errors were
pointed out).

I ended up taking the Maxmind free database and writing a perl DNS
server to feed it.  The free database is updated once a month and that
is good enough for my uses.
