Apache Web Server changes the syntax for IPv6 connections to

where the [ and ] are literal characters.

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.
