ip_range_start, ip_range_end, autonomous_system_number, autonomous_system_organization and ip_range_end are either IP addresses, or IP addresses in numeric format (depending upon which files you choose) and these two fields represent an inclusive range of IP addresses for that data row.
For example, in the -ipv4.csv files, the CSV line: 1.0.0.0,1.0.0.255,AU would mean that any IP addresses between 1.0.0.0 and 1.0.0.255 (inclusive) are AU. In -ipv4-num.csv files, the equivalent line would be: 16777216,16777471,AU.
For example, in the -ipv6.csv files, the CSV line: 2001:200::,2001:200:ffff:ffff:ffff:ffff:ffff:ffff,JP would mean that any IP addresses between 2001:200:: and 2001:200:ffff:ffff:ffff:ffff:ffff:ffff (inclusive) are JP. In -ipv6-num.csv files, the equivalent line would be: 42540528726795050063891204319802818560,42540528806023212578155541913346768895,JP.
Please be careful when using IPv6 and IPv6-num files in your program, the numerical value exceeds 32bit unsigned integers, and you would need to use a 128bit unsigned integer.
autonomous_system_number is a unique number assigned to an Autonomous System (AS) by the IANA. wiki).
We are using this database to get AS number from ipv4 address for asn.

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.
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.

In the case of a web application, you must include a link back to DB-IP.com on pages that display or use results from the database. You may do it by pasting the HTML code snippet into your code: IP Geolocation by DB-IP.

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.
