Mikael, I agree with your points and echoed them in my earlier reply. 6to4 is out there and is likely not to go away any time soon. Folks should definitely see what 6to4 relay they default to, you might be surprised (or not). FWIW - I updated ARIN's wiki for 6to4 relay deployment with some generic updates. I will add some more text shortly that folks may find useful if they decide to deploy their own 6to4 relays. John On 8/29/10 3:19 AM, "Mikael Abrahamsson" <swmike@swm.pp.se> wrote:

In most cases, we observed that 6to4-enabled operating systems and devices were attempting to use a 6to4 relay infrastructure hosted by a midwestern university.
Before that they used our (Tele2) 6to4 relays in Amsterdam and Paris. I think this was discussed here 1-2 years back.
I couldn't find it, but <http://gpshead.blogspot.com/2009/01/consumer-router-ipv6-firewall-fail.html> says the same thing.
I urge more people to look up what 6to4 relays you're using and set up your own if needed. People *are* using it and you not doing it is making things worse for your customers. Yes, 6to4 is generally bad but it's out there. Everybody needs to think about it.
