IPV6 Health Check
IPV4 addresses have been exhausted. We should double check that we are okay for IPV6 and make the required changes needed for better IPV6 support.

isc-dhcp-
- Works fine for dhcpv4 (dhclient -4 -d eth0)
- Works fine for dhcpv6 (dhclient -6 -d eth0)
- Included by default on CDs but not installed. So required: anna-install isc-dhcp-
- Current default dhcp client is busybox's udhcpc. As we ship isc-dhcp-
- It's to be noted that the mini.iso image doesn't contain isc-dhcp-
Meeting notes:
The IPv4 address space has been depleted, look at what's required in Ubuntu to get the ipv6 stack in good shape.
* IPv6 is urgent everywhere...
* Installer support
- Dual stack and IPv6 only
-- http://
- DHCPv6 (both in installer and after)
- NFS
- UFW - supported
- Issues with consumer grade hardware
Pre-meeting notes:
Renamed to a foundations spec, as this is a core issue for Ubuntu and it's derivatives -robbie.w

- Security and privacy are important. Maybe you should enable the Security Extensions for IPv6 by default? Win XP, Vista and Win 7 do so by default and iOS since version 4.3. Most certainly Ubuntu should do so as well. Source (in german): http://

Some extra things to consider in discussion contributed by Erik Andersen:
- check support for ipv6 in PPPoE (NM-specific) (mentioned on NM bugzilla, see https:/
- providing a way for users to enable/disable ipv6 privacy extensions (see bug 176125)
- verify / make UFW IPv6 ready (jdstrand: it's ready-- been in ufw since the beginning, with improvements all along the way) (erik-b-

Foundations-related topic to discuss:
- Whether or not we should support the IPv6-only use-case (ie, not dual-stack)
- Installer support: d-i/netcfg, etc.
- NFS: replacing portmap with rpcbind (if needed) and making sure we have all the bits and pieces. Right now, nfs-utils is compiled without --enable-ipv6.
- Status of DHCPv6
- How well the various interpreted languages (Python, Perl, Ruby, PHP, Go, etc) supports IPv6
Non-foundations related topic that might be of interest:
- Making the Ubuntu network infrastructure (archive, web site, Launchpad, etc) reachable by IPv6
- Creating automated test-case for IPv6-only configuration
- Are all the major clients/daemons in main IPv6-capable? Should it be made a requirement?
- libvirt IPv6 support seems broken (not sure)
Testing:
- Ubuntu should ideally work identically with IPv4-only, IPv6-only, and dual-stack setups, including cases where one of v4 or v6 is broken (not connected to the internet), and work with all the possible router advertisement/
