ULA is LOCAL.
It has nothing to do with PI.
People need address space to number the links between their SQL and
web servers. This is completely orthogonal to address space used on
the internet.
ULA is also UNIQUE.
(Well, for half of ULA, "probably unique").
It would be a service, rather than a disservice, to the community of
"network admins" (LAN admins), to educate them on the value of uniqueness.
And to point out the existence of a suitable replacement for IPv4's
10.0.0.0/8 et al, if they want a non-registered, non-unique, truly
non-routable address space that maps well to their current RFC 1918 space.
And that would be the IPv4-mapped IPv6 address space for RFC 1918.
I.e. ::ffff:10.0.0.0, ::ffff:172.16.0.0 and ::ffff:192.168.0.0 (as /104,
/108, and /112 respectively.)
And yes, I know it's ugly and rude.
But it makes it easy for the end admin to manage the dual-stack universe
between their SQL and web servers.
