Hi,
I just received the draft minutes of our working group session during
RIPE 58.
I would appreciate if you could take a look at them. Please send
requests for correction directly to me and Susannah and we will make
sure they will get included in the final version.
The minutes will be declared final by Friday July 10 if no comments
are received that require another last call.
A big thanks to Vesna for the detailed and high quality minutes!
David Kessens

A. Administrative Stuff
David Kessens (WG chair) went through the agenda:
http://www.ripe.net/ripe/maillists/archives/ipv6-wg/2009/msg00009.html
B. Developments/Initiatives Regarding IPv6 in the RIPE Region and Beyond
B1: IPv6 peering BoF
Paul Hoogsteder, Breedband Delft (community network)
Paul announced that an informal session between old and new IPv6 peers
would take place on Wednesday, 16:00 near the cloakroom.
B2: Rumy Kanis, RIPE NCC, Training manager
Rumy made a brief announcement that the RIPE NCC Training Department is
busy recording testimonials from people in the community who have
hands-on experience deploying IPv6. She asked if anyone is interested in
being filmed and interviewed about their experiences with IPv6, they
should contact training(a)ripe.net
C. RIPE NCC IPv6 update
http://www.ripe.net/ripe/meetings/ripe-58/content/presentations/er-ipv6-rip…
Erik Romijn, Information Services
Erik announced that all of the RIPE NCC's external services have been
available over IPv6 since January 2009.
Lorenzo Colitti (Google) mentioned that one service does not support
IPv6 - the socks proxy. It's internal only though.
Erik said that he was only referring to public services.
Patrik Falstrom asked if ROSIE (the RIPE Meeting website) counts as a
non-external service?
Erik responded that all ROSIE content can be accessed over IPv6 through
the www.ripe.net web page, so you can actually see everything on ROSIE
without having IPv4.
Mohsen Souissi, AFNIC, asked how do you think you can motivate the
operators managing the reverse delegations for IPv6 to get the transfer
active for you so that your Hostcount++ will work in IPv6? Do you have
any strategy to get it better than zero?
Erik said that the first step is to get a zone transfer from a TLD.
Mohsen said that the first step is reverse delegation.
Andrei Robachevski, RIPE NCC, said that, for IPv6, we do not reverse
DNS. We have to do this for IPv4. Because we can't transfer all the
forward zones, we are just numerating all reverse zones. We can't do the
same for IPv6 because IPv6 reverse DNS is big and sparse. So, the real
problem here is that we have difficulty in actually transferring forward
zones and therefore, we have difficulty counting IPv6 addresses there.
He continued that the RIPE NCC's strategy is to convince operators to
open the Access Control Lists (ACLs) for RIPE NCC IP addresses the zones
can be transferred.
For those operators who have some privacy issues or other
considerations, we have developed a do-it-yourself kit to give to ccTLD
operators. This software will count the hosts, anonymise the data and
ship data back to us.
An attendee asked that, since this is related to forward DNS, do you
think it's a good idea to contact ccTLDs?
Andrei responded that the RIPE NCC is using this idea but it's not 100%
successful.
David Kessens asked if there was an explanation for the huge number AAAA
requests?
Anand Buddhdev (RIPE NCC). Those quad-A queries are anomalous. They
originate from broken versions of BIND. We suspect somebody is abusing
them to send queries to the root.
Gert Doering asked what about the RIPE NCC's internal network and the
workstations? Macs are v6 capable. Are you keeping it on, between
people working there and your internal services, or are you afraid of that?
Erik said that on the RIPE NCC's wireless network, IPv6 is switched on
and there are no problems.
Gert said that that was his experience too: it just works.
D. Google IPv6 update
Lorenzo Colitti, Google
Lorenzo explained that public IPv4 address space is going to go away.
There is a business case for IPv6 because the alternatives are expensive.
There is also an opportunity here - there is going to be a large pool of
devices that will only be accessible and able to access using IPv6. If
you are a content provider, then you might want to talk to them which
means you need to have IPv6.
It took google about a year-and-a-half to go from zero to being able to
serve most services over IPv6. And we keep adding new ones. And with a
very, very small team - just a handful of people.
He continued, saying that if you are an exchange point operator or if
you are an ISP, please do not charge separately for IPv6. Please absorb
this cost in other ways because charging separately will hinder adoption
and users and traffic can appear overnight.
Extra data - measuring IPv6 query requests over IPv6:
0.25% of the total is over IPv6.
0.10% is over native, or not tunneled, IPv6.
2/3 is the proportion of requests that we serve as Google over IPv6. So
two thirds of native IPv6 Internet appears to be enrolled in "Google
over IPv6" program.
Mat Ford (ISOC) commented that the "Google over IPv6 program" does not
scale. He asked at which number of your users who would be affected by
not being able to reach www.google.com over IPv6 do you say "I don't care"?
Lorenzo answered that he did not don't but the magic number seems to be
10%. It depends on how situation evolves. We need to see better data on
the "brokeness". It's hard to measure.
Kostas Zorbadelos (OTC Greece) asked do you use the same load-balancing
mechanism in IPv6 for IPv4.
Lorenzo answered that Google tries to use the same infrastructure for
both IPv4 & IPv6. The load-balancers are the same. Deploying separate
hardware for IPv6 is not a good idea.
Jasper Wonnink (fix6.net, via Jabber)asked when will the Google bot
start crawling over IPv6? When there is AAAA available?
Lorenzo stated that Google is working on this.
CK Claffy said that he objected to Lorenzo's statement "Just because we
can't see the traffic, that doesn't mean that IPv6 is not really
happening". As a scientist, the traffic is the only measure that IPv6 is
really being used.
He said he knows how hard it is to measure the traffic and to get the
traffic numbers but we should not be believing PowerPoint slides. This
has has led us into a global telecommunications crisis, because we
believed in numbers like "traffic is doubling every 90 days". That's a
global example of how important is it to get traffic numbers, and what
happens if you don't.
He continued that the EU is going to conduct a survey. He said he wanted
to make it clear that a survey is a substitute for the truth. It's not
actual data.
Lorenzo responded that CK was correct. He said that what he meant was do
not expect smooth growth of IPv6 traffic. We are moving traffic from
IPv4 to IPv6 because the user stacks, all else being equal, will prefer
IPv6 to IPv4.
KC said that he thought it would be good if Lorenzo's graph about IPv6
traffic had a Y axis with numbers and labels so that I could tell it
wasn't going from 0 to 0.002.
Lorenzo noted this.
Gil Mason (Altna, via Jabber) asked how Google defines production
quality? When is a network good enough to to be allowed to connect to
Google over IPv6?
Lorenzo responded that when we have a good connectivity and when the
network is well supported. We like to see that the infrastructure is
common, so that we don't get IPv6-specific failures.
Randy Bush (IIJ) said that measurable spikes can be seen, as large
customers change something - the way DNS resolves, client roll-outs,
gateway services etc. He continued that it depends on what kind of
electronic microscope you are using. There's very little traffic.
Google's measurements are as useful as any other I've seen.
Lorenzo said that 0.2% is coming over IPv6. There are daily patterns,
not only spikes.
KC added that there are no *numbers* in this data. we need to
acknowledge what is the limitation of the data we are making available
and what data we would need to answer the question for real.
Lorenzo answered that client penetration is also a reasonable measure,
or at least a measure we want to track.
Mohsen Souissi said congratulations but the presentation is not serving
the community because, if taken out of context, it does not make clear
that this is just one of the measurements tools, and that you do not see
all the traffic, nor other servers that get deployed every day.
Lorenzo: These numbers only reflect IPv6 clients connected to our web site.
Jasper asked if Google would roll out IPv6 for www.youtube and when?
Lorenzo said that Google was working on all services but there are
limitations in the hardware developer's time. It will come at some point.
E. Report(s) about *actual* v6 traffic volume as compared to v4?
*what's real* out there, not what's on Powerpoint? (input from the
audience)
Martin J. Levy,n Hurricane Electric
http://www.ripe.net/ripe/meetings/ripe-58/content/presentations/hurricane-6…
Martin explained that real traffic numbers are available in my slides from
the Google IPv6 conference.
He continued that in his network, they do not have the same customer base
on IPv4 and IPv6. Our stats about IPv6 can not be compared with IPv4.
I want to show 6to4 and Teredo traffic. 6to4 is not a bad protocol.
Teredo is a horrible protocol.
On our backbone, we introduced several 6to4 relays, and localizing
traffic made a big difference. It peaks at 20 Megabit.
On Teredo, we were seeing hundreds of megs of Teredo traffic moving
around. We deployed a Teredo service over the whole network, from 3 to 13,
geographically dispersed. We were peaking around 150 megabits. Now we have
200-300 Megs of predominantly end user to end user traffic.
The easiest way to get rid of the Teredo, is to enable IPv6. It may be a
great measure of how many people want to access v6 but don't have it.
An attendee asked how can we get rid of the horrible Teredo protocol?
Martin answered that running stable relays will get us though this
transition period.
Randy Bush (IJJ) said that the optimist thinks the glass is half full; the
pessimist thinks the glass is half empty. The engineer knows the glass is
too big.
Martin answered the majority. We had to run 6to4 on every Teredo relay, on
the same box, or next to each other.
An attendee commented that he does that with a dedicated connection
between them.
F. Global IPv6 routing table status
http://www.ripe.net/ripe/meetings/ripe-58/content/presentations/v6-routing-…
Gert Doering
Gert gave the routing table report. He asked are we growing fast enough?
and said no, we are not.
David Kessens said that the advantage is that we have time to talk about
that issue at the next meeting.
H. Overview of ISOC's current activity with regard to IPv6 deployment
http://www.ripe.net/ripe/meetings/ripe-58/content/presentations/isoc-ipv6.p…
Matt Ford, ISOC
I. Proposed EU IPv6 survey
http://www.ripe.net/ripe/meetings/ripe-58/content/presentations/proposed-eu…
Maarten Botterman
GNKS Consult
Maarten explained that there was a commitment from the government to help
make this happen, but for them to know what to do, they need to know where
they can help the best.
He said that the European Commission has contracted TNO to carry out
deployment monitoring activity. There will be a survey conducted in June.
He said that a draft survey is available for feedback.
The results on an aggregate level will be public, and will be used for
information to the European Commission on their policy preparation.
Please contact maarten @ gnksconsult.com for more information.
Mohsen Souissi (AFNIC) asked if there is any initiative to harmonise all
those various measurements to have common understanding about what do we
measure, what the methodology is etc?
The tool was published at the last RIPE meeting. There may be many
others. I feel frustrated, because there is no overall picture about who
measures what.
Maarten agreed.
Leo Vegoda (ICANN) asked if Maarten meant RIPE NCC members only, or the
15,000 other organisations that have resources from RIPE NCC, but are not
members?
Maarten responded that he also meant non-members; anyone in the RIPE
community.
Leo said the RIPE Community are not the only people who are operating
networks in Europe. Will you take a list from ARIN too?
Maarten said no, the scope of this survey is limited.
David Kessens made a few final comments: we are an operators'
group, a technical forum, but it's also important to make sure
that policy makers, decision makers and governments are well informed
about the challenges that we are going to face in the next few years
regarding this IPv4 exhaustion.
He added that this is one of those projects that can contribute
tremendously there, because it's basically an interface between those two
worlds. So, I would very much like to encourage people to fill out the
survey.

Dear Colleagues,
This is a reminder that the IPv6 Deployment Monitoring Survey is
online, and we encourage all members of the RIPE community to
participate.
The final date for submitting a response is Friday, 3 July 2009.
You can access the survey at:
http://is-nri.com/take/?i=150597&h=1GwWe3dXXMcPrRrOw5s2yg
The survey is being conducted by TNO and GNKS Consult, working with
the RIPE NCC and sponsored by the European Commission. The aim of the
survey is to collect data on the current and future use of IPv6
throughout the RIPE NCC service region.
The survey is composed of 16 questions and can be completed in 10-15
minutes. Results will be presented and discussed at RIPE 59 and
published on IPv6 Act Now:
http://ipv6actnow.org
For more information on the IPv6 Deployment Monitoring Survey, please
see:

Dear Colleagues,
As announced at RIPE 58, TNO and GNKS Consult are working with the
RIPE NCC to conduct a survey, sponsored by the European Commission, on
the current and future use of IPv6 throughout the RIPE NCC service
region.
The IPv6 Deployment Monitoring Survey is now online, and we encourage
all members of the RIPE community to participate:
http://is-nri.com/take/?i=150597&h=1GwWe3dXXMcPrRrOw5s2yg
The purpose of the survey is to better understand where the community
is moving, and what can be done to ensure the Internet community is
ready for the widespread adoption of IPv6. The survey was developed in
consultation with members of the RIPE community, and is inspired by
the 2008 survey conducted by ARIN and CAIDA in North America. It is
sponsored by the European Commission, which has actively supported the
adoption of IPv6, in the interests of innovation and the continuing
competitiveness of European industry.
We encourage all organisations in the RIPE NCC service region to
participate in this survey, which we hope will establish a
comprehensive view of present IPv6 penetration and future plans for
IPv6 deployment. By making the survey design similar to the ARIN/CAIDA
survey, we hope that the results will contribute to a better global
picture of current and future IPv6 deployment.
The survey is composed of 16 questions and can be completed in 10-15
minutes. For those without IPv6 allocations or assignments, or who
have not yet deployed IPv6, the questions will be fewer in number.
The survey will close on 3 July 2009.
Results of the IPv6 Deployment Monitoring Survey will be presented and
discussed at RIPE 59, which will be held 5-9 October in Lisbon,
Portugal. Results will also be published on IPv6 Act Now:
http://ipv6actnow.org
Please provide your name and contact information on the survey form if
you wish to receive the draft survey analysis when available. Please
also indicate whether you are willing to share additional data with
the TNO and GNKS Consult IPv6 Deployment Monitoring team.
We appreciate your time and interest in completing this survey. If you
have any questions concerning the survey, please send an email to <info(a)gnksconsult.com
>.
