[ipv6-wg] RIPE 69: Test your gear and software without IPv4!

Hello and welcome to London,

This message probably only has relevance if you are visiting the RIPE 69 Meeting, But feel free to continue reading even when you are not.

As you are setting up wireless you may have noticed a network called ‘IPV6ONLYEXP’. This network is once again setup so you can see if your applications hold up in an environment that only provides you with an IPv6 address. The password is in the bottom of this email.

Please note: This network is provided as-is and on a BEST EFFORT basis, the RIPE NCC will NOT PROVIDE SUPPORT.

Of course the main functionality will be monitored and acted upon when things go wrong, but ops will be unable to help you with devices or software configuration and/or troubleshooting.

The network has a NAT64 gateway attached, which means that you should be able to connect to the whole Internet, even when the service does not support IPv6 yet. This also means that some applications will be confused and complain there is no connectivity, even when there is. This is exactly why we have this setup running, you can find out for yourself what works and what doesn’t.

If you find an issue, please feel free to share it on this list. Even more important however, please also file a bug report or send a notification to the creators, so they are aware and hopefully can make it work in the next release.

Of course, since we have done this before, we have a few know problems:

- For NAT64 to work you must make use of the resolvers as advertised by the network, these are patched to do the translations
- A wide variety of Android devices will not be able to pick up the advertised DNS servers and while connected, will fail to work properly
- Skype does not work! 
- A number of IOS apps will complain there is no network, while they actually do work, please try what happens if you ignore those pop-ups

So good luck and enjoy the meeting. If you do have questions or want to chat about it, please use this list or find me or Andrew Yourtchenko on site.

I would like to thank RIPE NCC, especially Menno, Razvan and Marco v T for helping out and making this possible.

The password is “iknowbesteffort”, this is different from the main meeting password :)

See you in a bit in London,
