My take is that sunset is a great name.
I would have loved to learn in this group a few things:
- is there a process in place that gives back to IANA the unused IPv4
space. How much is this process used?
I believe each RIR has a separate process for the return of unused space.
https://www.apnic.net/manage-ip/manage-historical-resources/returned-ipv4-address-space/
https://www.arin.net/resources/return_revoke.html
etc.
It's used rarely, but somewhat; when an organization stops paying their
bill, the RIR might reclaim the addresses.
Most organizations in most regions would rather sell their unneeded IPv4
addresses, since prices are rapidly approaching US$20 per address.
- why new technologies and sites get invented yet IPv6 is not on them
(deployed IoT w/ IPv4, self-driving cars w/ IPv4, new big office
buildings w/ IPv4, and so on).
1. Shortsightedness
2. Developers hacking together what they barely know
3. Using an OS designed for embedded systems that's based on a very old
Linux without IPv6 support.
- in 5G why there is no GTP replacement using QUIC instead of UDP and
IPv6 instead of IPv4.
5G is still in development, but I really don't know.
And, my last question, my most preferred, which I know is polarizing,
soo feel free to ignore: why does not IETF put exclusive content on
IPv6? Generally speaking I have never heard of some highly
interesting content that is available on IPv6. When that happens
immediately somebody puts in on IPv4 too.
Because as an open body, IETF content must be available to everyone, and
not everyone has IPv6.
Any general content will need to be available over IPv4 until at least
2024, when 90% or more of the world is IPv6-capable. Within the next
couple of years I can imagine a phone app designed exclusively for users
in the US that was only IPv6-capable, since US mobile is nearly all
IPv6. Same for India, maybe, and a few other countries.
those DC also are almost always closed proprietary environments (even
if the
components are open source, I can't buy a cabinet in that space, and
they
don't run off-the-shelf OS builds).
It seems though they can be accessed on the Internet, right? I mean
such a data center can be accessed freely on IPv6, and for a fee put
content there. That content would not be available on IPv4.
No: examples include Facebook and LinkedIn, which have very functional
edge translation from IPv4.
I think the next step would be to have free upload capability (like
drive.google but w/o IPv4).
Well, there was a marvelous presentation by Mythic Beasts at v6ops at
IETF101-London.
https://datatracker.ietf.org/meeting/101/materials/slides-101-v6ops-ipv6-only-hosting-00
But if what you want is for someone to sacrifice their revenue or
increase their costs For The Good of IPv6, I would not expect that to
happen.
I think that we wanted to be premature, such that we could get OS
vendors
to test having no IPv4 *now*, and not discover things are broken ten
years
later when the equipement can't be replaced. We actually spured a
few OS
vendors (FreeBSD, Linux, others) to try the test... many discovered
"127.0.0.1" hard code in many places.
In the end, the problem is that funded OS vendors at the IETF has been
"reduced" to Apple and Google, neither of which is in the desktop market
it seems... While MS is clearly still here, funded Linux
OS/networking people
are not at IETF (Wouters excepted!).
So sunset4 did as much work as it could without broad OS vendor
consensus.
I believe that the situation will change once more operators begin to
attempt to really turn off IPv4 in a non-3G space.
Please keep the list alive.
I agree.
And make new inspiring stickers :-)
I have some for Montreal, even though I won't be there. :-)
