A lot of IP lookups only query ARIN, this is a quick and easy example how to query the correct whois databases to get the IP address network owners This code sample takes the IP address and the host and gets the AS Number and details from AFRINIC, LACNIC, RIPE, ARIN OR APNIC.
- Run the sql file on the database, replacing "databaseName" wiht the name of your database.
- Run code.php and you will see a sample from LACNIC
The dataset was adopted from IANA: https://www.iana.org/assignments/ipv4-address-space/ipv4-address-space.xhtml
