I agree with Karl. We use the ULA space for our internal test labs. The /48's we have in use get routed around internally but have no chance of leaking to the internet.

both ways - if we decide to use it we'll have to either overlay it with public IPv6 space (and provide the NAT/proxy for where we don't have any public IPv6 assigned) or simply not use the fc00::/7 and skip the NAT/proxy aspects of it.
There is no necessary link between ULA addresses and NAT. You don't have to NAT ULA, *ever*. If you need public addresses, go get them. There are enough. IMHO one should use ULA in only three situations: - a completely isolated network - for internal communications e.g. fabric management) - for testing Regards, K. -- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Karl Auer (kauer () biplane com au) http://www.biplane.com.au/kauer http://twitter.com/kauer389 GPG fingerprint: E00D 64ED 9C6A 8605 21E0 0ED0 EE64 2BEE CBCB C38B Old fingerprint: 3C41 82BE A9E7 99A1 B931 5AE7 7638 0147 2C3C 2AC4
