Good morning everyone,
a follow up from the RIPE83 IPv6 WG meeting: I had a few talk afterwards
and at I got the feeling that "not to ULA, but to GUA" would be the most
sustainable way forward.
## Motivation
The Motivation is:
- with GUA, potential connectivity to the Internet later does not
require renumbering
- with GUA, reverse DNS is easily possible
We had a bit of a discussion on the IETF mailing list before [0]
and this comes with the obvious question "who is going to pay for it",
where "it" is mainly related to building, maintaining and supporting such
space.
## Target Audience ("consumer")
The target audience is "organisation who cannot afford to become an
LIR" [1], because if an organisation can become an LIR, they preferably
should.
## Target Audience ("provider")
Coming back to the who is going to provide such a thing, I believe this
might require sponsoring from one or more organisations. Obviously
ungleich as an Open Source/IPv6 provider is in for this, but I think it
would be beneficial if a couple of "core members" would drive such a
project.
## Project structure
In particular I imagine a free GUA service to be split into two phases:
* Initial setup (see below)
* Running / Maintenance / Support
## Initial setup
As the ULA registry [2] is fully open source and a django project, it
could potentially be used as a code basis. Aside from the actual
self service portal, other issues need to be addressed:
* Integration with the RIRs (mostly: whois DBs)
* Definition of policies
* Definition of support channels
## Running / Maintenance / Support
Now in the spirit of GUA space for community projects, I would envision
not *one*, but potentially *many* free GUA registries, potentially using
the same code base, but offering different policies. This would allow
registries with different objectives:
* A free GUA registry for a particular territory (f.i. "North of Swiss Alps")
* A free GUA registry for a particular target group (f.i. "Only for hackers")
* A free GUA registry with non-monetary conditions [3]
And this brings me to the final aspect:
## Decentralised, free GUA registries
IPv6 can be a real enabler for decentralisation, because everything can
be made accessible. The very same principle also applies for a free GUA
registry: instead of having one free GUA registry, nothing would speak
against having multiple of them. As a matter of fact, it might even be a
good tone as an involved LIR to provide some free GUA space. Anyone
thinking of HE.net right now? Yes, that's the direction I am thinking:
Free GUA registries as a concept that can easily be cloned and
re-applied.
## Next steps: RFC / CfP
So how to go from here? I would be interested in an exchange on this
mailing list and also to hear if there are other parties here that would
be interested in helping out, either by
- reviewing the proposal,
- coding,
- helping in the policy area,
- supporting the first free GUA registry (read: handling support requests),
- maintining the first free GUA registry (read: keeping the platform
up-to-date),
- or contributing financially
One of the unclear items from my side is whether or not there should be
some governing organisations like a foundation, but I guess this can be
clarified on the way.
All that said, I am very much looking forward to hearing your opinions.
Best regards from 50cm of snow[4],
Nico

[1] Community networks, NPO, NGO, Maker spaces, maybe even SME are target
groups that come to my mind / are organisations I talked to.

[3] I don't want to elaborate to much on this one already as it has a
lot of discussion potential - but the motivation is as follows:
community projects usually don't have money, but time. So instead of
having users pay some kind of a fee by time, a payment by "proof of
work" might be feasible. The details of such an arrangement can be
complex, but there might also be easy solutions for it. To be
discussed & decided.
