arpReach V2 introduces IPv6 support for the purposes of geo-location.

IPv6 support was never included, nor will it be added, into MySQL 5.5.X.

arpReach V2 users on MySQL 5.5.X will get the error. The elements of the error message include:

Your database table name will prepend <table>.INET6_NTOA

A Database Error Occurred

Filename: libraries/datamapper.php

Error Number: 1305

Line Number: 1346

The Solution:

MySQL should be updated to at least MySQL 5.6.3 (or MariaDB 10.0.12 +).
