ASN database Update: Daily

Created by merging 5 RIP (afrinic, apnic, arin, lacnic, ripe ncc) IP-ASN-Country database. ASN (Autonomous System Number) is a unique number assigned to an Autonomous System (AS) by the IANA.

DB-IP database Update: Monthly

You could download and read the license from ip-to-asn-lite or ip-to-country-lite or ip-to-city-lite. Most of the AS Organization name used in asn uses ip-to-asn-lite database. We also use ip-to-asn-lite to get AS Number from ip address as a supplemental.

Merge rule for multiple database

When merging multiple database, set the front database above back one. For example, geo-whois-asn-country is created by merging 3 database with GeoFeed > Whois > ASN. In more detail, the geo-whois-asn database matches the GeoFeed results, for ip ranges not covered by GeoFeed it matches the Whois results, and for ip ranges not covered by either it matches the ASN results.

GeoFeed: 1.0.0.0, 2.0.0.0, AU
         3.0.0.1, 4.0.0.0, US
Whois:   1.0.0.0, 2.2.0.0, FR
         2.5.0.1, 4.0.0.0, IN
ASN:     1.0.0.0, 4.0.0.0, JP
