Use of unique local IPv6 addressing rfc4193

[Pshem Kowalczyk <pshem.k () gmail com>]

Hi,

We're looking at rolling out IPv6 to our internal DC infrastructure. Those
systems support only our internal network and in the IPv4 world they all
live in 'private' space of 10.0.0.0/8. I was wondering if anyone uses the
fc00::/7 space for these sort of things or do ppl use a bit of their public
IPv6 allocation and manage the security for those ranges?
I realise I'd have to use a proxy or NAT66 for the regular outbound
connectivity (but we do it already for IPv4 anyway). The truth is that even
if we do use something out of our public allocation we're likely to do the
same thing (just to be sure that nothing spills out accidentally).

So what do you do in this space?

kind regards
Pshem
