I started to play with sqlippool and have a couple of questions.
Does sqlippool or any other module supports IPv6? I haven't found 
anything about it in the documentation.
Is ippool module used only as example for database schema? It looks like 
it doesn't need to be enabled for sqlippool operation.

Kind regards,
Andrey
