I was wondering if it would be possible to run parts of the TERENA Secretariat office network on IPv6 only.
Our office has a /24 IPv4 and a /48 IPv6 network since 2003, and all our public services are available on IPv4 and IPv6.
Since we have IPv6 internally for all clients, one native IPv6 connectivity in our office, it seems that the first step would be to remove IPv4 from services that are only used internally.
This page keeps track of progress, bugs, and issues.

BTW, this is not the first time this has been tried out. For instance Arkko & Keranen did some interesting work in 2010.

MacOSX Lion & Cisco AnyConnect

Late July 2011 Apple released version 10.7 of their OSX operating system, named Lion. This version has several major IPv6 related improvements, the most important I think is DHCPv6 support. This means that it is now possible to successfully run a Mac in an IPv6 only environment without any configuration.
Unfortunately for us AnyConnect has a serious bug on Lion, namely that there is no default gateway being configured for IPv6 upon connection.
Since we have several IPv6 only services these days, this is a true show stopper (sad)
What makes it worse it that the smbd in Lion has IPv6 support, and because our Windows 7 computers already support SMB via IPv6, this means that we could make our Samba server IPv6 only. But since AnyConnect does not work, this is not (yet) an option...
The issue has been reported already to Cisco and is filed as CSCts11510 (login required).
Rumour has it that a fix is available soon, so let's just keep our fingers crossed!

VPN supports IPv6

A new VPN setup: Cisco AnyConnect. Clients get an IPv4 and an IPv6 address from the office pools, so they can access all services via IPv6
