Dear MaxMind Support,
your GeoLite ASN database [1] appears severely broken. (probably by a recent code change on how AS names are collected)
Karsten Loesing from the Tor Project determined [2] that the amount of records with nameless autonomous system entries in your DB increased from ~500 (Feb 2016) to over 57000 in the current version (June 2016):
grep '"' -v GeoIPASNum2.csv |wc -l 57179
but the actual root cause probably affects *all* entries in the database.
After investigating weird AS names in your DB called "73-75 Dr. Staicovici" (AS8708) or "Warszawa 02-822" (AS12741), it appears as if you are using the first "descr" line instead of the actual AS name.
Example: AS Number: AS8708 AS Name according to MaxMind: "73-75 Dr. Staicovici" actual AS Name according to [3]: RCS & RDS SA http://bgp.he.net/AS8708#_whois

thank you for looking into this, nusenu (I'm not a member of the Tor Project)
