PD: In my opinion it should be /48 by default, static and opt-in to dynamic, no extra charge on top of the Internet service price, but I know many ISPs will not agree :-( Here just trying to collect the info in a single place.

My opinion is that anything between /56 and /48 is fine. As far as I know, current RIPE policy gives the ISP the option to without motivation, ask for enough IPv6 addresses to offer each customer a /48 and I'd like to keep it that way. But you're correct, it seems most deployments are going for /56 for no more reason than that it "should work for everybody". Of course /48 works as well as it's a superset of /56. I'm not going to give anyone who gives everybody a /48 a hard time and I don't want RIPE to do it either. -- Mikael Abrahamsson email: swmike@swm.pp.se
