mapping public to private IPv6 networks when firewalling

[Eugen Leitl]

The SOP for firewalling in IPv4 is to use
private (RFC 1918) networks and map external public
networks 1:1 to them. The idea is that defaults to
unreachable systems in case of firewall failure.

What's the address space to use in IPv6 for such
purposes? Is fc00::/7 (RFC 4193) unroutable on
the public Internet in the same way as RFC 1918
addresses?
