IETF71 IPv4 Outage

From $1

During the IETF71 meeting in March 2008, there will be a hands-on experiment for exploring the post-global-IPv4 Internet.  The plan is for this to be both:

  • a first-hand experience open to all IETF participants, and
  • an opportunity to capture informal experience data to inform protocol design work going forward.

One aspect of this  experiment will be to provide an "IPv6 only" network throughout the meeting week.   This will provide participants with the opportunity to "site see" the current realities of IPv6 network deployment.  Participants who so desire can use this as an opportunity to test their software, setup or services for IPv6 accessibility.   Computers connected to that network will be assigned an IPv6 address, and packets from that network will be routed (only) via external IPv6 connectivity.  That is, there will be no IPv6 to IPv4 translation or Application Layer Gateway support to connect to IPv4-only sites.   While the "IPv6 only" network will be available throughout the meeting week,  other wireless network access will be turned off in the plenary meeting roomduring a set time of the Wednesday night plenary meeting.  This will provide a focused  and communal opportunity for experiencing the IPv6 Internet!

We are also exploring the demonstration of another model of a possible IPv6-supported future, to provide two possible future paths for people to compare and contrast.  More information will be provided as that is scale tested and made available.


As you participate in this effort (through the week, or at the plenary event), please be sure to contribute any findings by updating the experiment information page,

Also, discussion is being logged on the IPv6-accessible Jabber conference:

ipv6-experiment on the jabber conference server

The transcript from this jabber record will be saved as part of the experiment record.

If you do not regularly use IPv6, you will need to spend some time configuring your system and getting used to the environment.  Specific instructions for setting up IPv6 on different operating systems are referenced below.  The "IPv6 only" network will be available throughout the week, and you will want to set up your system and test it before the actual "IPv4 outage" event on Wednesday night's plenary.

XP worked as expected. No DNS so I had to know the addresses. I've used IPv6 with XP every now and then.

LINUX - Well, I dual boot and haven't used the wireless with my compaq 8230 machine. Thus, I couldn't get my wireless operational. Apparently I need to download an additional RPM.
So, no LINUX results.

I hope they continue to have IPv6ONLY SSID and perhaps something that runs V4 hosts through V6 only networks to test translation as their appears to be much work starting in that arena.
