Looks reasonable to me - just a couple minor questions.
Have you given this a spin on a racklette? (Can we, before merging?)

Do we want to check that the low 72 bits are all 0? That's guaranteed for our random ones, and converting the subnet address into an Ipv6Net<56> will do that, but it may indicate some confusion if an operator asks for it?

I think that's a reasonable check to add, as it does make things a bit clearer in terms of what we expect (and what the system will do if you set the lower bits of the address)

Do we want something like "(will be chosen randomly)" instead of leaving it blank?

I think this is also a good idea
I'll do that today! |

LGTM, assuming the racklette testing went well

Tiny nit - why is this string different from the one a few lines up?

I figured we wanted it to say "will be chosen randomly" if the user hasn't provided a ipv6 subnet address and we are still uninitialzed, but it should say "chosen randomly` once we are initialized.
This is how it looks when None maps to "will be chosen randomly"
It seems like it could be a little confusing to users if we left it that way.

Ahh, got it. Yeah that works for me 👍

Here's how it looks with the two different strings:
Before Rack Init
After Rack Init
With User Specified Address
help rustfmt with long strings :D Co-authored-by: John Gallagher <john@oxidecomputer.com>

To pave the way for a multi-rack world, we are replacing the static
fd00:1122:3344::01prefix with a randomly generated one or a user specified one, that way racks can have unique addresses once they start talking to each other.fd/56Related
