We don’t need IPv6
We don’t need IPv6
Originally the title was
“We don’t need IPv6”
Including the “”
We don’t need IPv6
I hereby suggest that we
should use more NAT (NATs are good, NATs
provide security)
Use 240/4 address space
IPv6 is just to complicated
Just kidding!
/me
I’m using IPv6 for about 3.500 days
finished first big IPv6 project around June 6

th
2012?

nd
World IPv6 Day
Back the we had discussion about when the
majority of systems one the Internet would be
reachbale via IPv6
I think 2018 was among the answers
So why this talk in 2018?

After some more sorting I started to ask why

for the rest of the talk
Answers (I)
“It's mostly in our sysadmins' hands, though has
at least made some progress lately! “ -
launchpad
“I'm afraid we're not able to discuss our
roadmap publicly, but I will go ahead and add a
+1 for this feature to our internal feature request
list :)” - github
Answers (II)
“When/if there appear ipv6-only networks that
have trouble reaching sourceware.org, this
issue may become ripe. Until then, it seemslike
a non-problem” - sourcemaster
“The hosting provider I use still doesn't support
IPv6. I have mentioned about it to them in a
feedback questionaire they made a few years
ago. I have no plans to change the hosting
provider.” - tukaani.org
Answers (III)
“IPv6 support is on our roadmap. However, we
have no firm ETA at this time. We recognize
that IPv6 support is increasingly important, … “
- sourceforge
“Last year we deployed a new set of servers
that among other features will provide full IPv6
support to all our services. We arecurrently in
the process of migrating virtual machines into
the new servers, and upgrading their software.”
- gnu.org
Checking CentOS
I tried the same test for CentOS using the
“homepage” in the rpm spec
~ 1000 unique URLs
~ 750 not reachable via IPv6 (~50 NXDOMAIN)
Needs some further testing and I will not ask them
all about IPv6 support
Asking more Questions
Hotel and Airport Wireless Network Operators
“Nobody asked before”
“We don’t have any plans for this”
“Now that you are asking we may think about it”
“From our last 5.000.000 customers you are the 2
nd
to ask. …. We’ll start rolling out IPv6 in July”
IPv6 and customers
Project -2:
If you wanted to get some people angry you just
had mention “IPv6”
Project -1:
Everybody busy moving to the cloud, network IPv6
ready for years, seems you don’t need IPv6 for a
large Internet portal
current Project:
IPv6 is one of things I’m working on
As a small content provider
blog.quux.de only has AAAA record – people
are telling me that I might have forgotten the A
record
Running a wiki and a mailing list for some nerds
Asked if I can make the the wiki host IPv6 only
Will ask again in 20years
Conclusion...
Most people are aware of IPv6
Some people don’t care
Some people choose to ignore the problem
Some people haven’t notice / have forgotten
that IPv4 addresses are scarce
It’s still a long way to go
When nobody asks about IPv6 nobody sees a
demand for it
Idea
Set up a website an coordinate the asking part

So why this talk in 2018? Sometime ago on twitter:

Can we build LFS on an IPv6 only host? (I) Some scp, cut, sort later I came up with a list of 32 unique URLs Using curl and some shell I ended up with a list of 18 unique URLs not supporting IPv6 After some more sorting I started to ask why You might want to open https://ipv6bingo.com/ for the rest of the talk
