Quite a lot of structural changes would be required:

• player ip
• ip banning
• ip range banning
• bminfo

http://dev.mysql.com/doc/refman/5.6/en/miscellaneous-functions.html#function_inet6-aton

But requires MySQL 5.6.3 minimum and would also require converting from int columns to varbinary.

I got this error when a player joined server with ipv6 address.

it looks like the plugin doesn't recognize the ipv6 address.

That's why this feature report is still open ;).

would there be a solution in the foreseeable future?
could you pls fix it, that woul be very nice.
