~~fc00::/7 are ULA (basically what RFC1918 was for IPv4)~~ not entirely true, fc00::/8 is part of ULA, but it is not yet defined. Use fd00::/8 instead.
2001:db8::/32 is for documentation purposes

You're not supposed to use fc00::/8, so it's just the fd00::/8 half that's the new ULA.

Didn't know that, thanks. Luckily, I've only ever used fd00::/8
