I think this is mandated by one or the other RFCs, it's not just an 
Apache thing.

I'd suggest that your question actually has two parts:

i)   If a server name only resolves to an IP6 address, does fcl-db 
honour it?

ii)  If a server is specified by IP6 address ditto.

I've written something that was specifically IP6-aware but can't 
remember whether I investigated the behaviour of the backend servers 
(PostgreSQL and Firebird) which were assumed to be local (RFC 1918 
addresses). I do remember vaguely that there were issues with the OS or 
libraries (Linux etc. in this case) mapping IP4 onto part of the IP6 
range when both were in use.
