Comment 1 for bug 369008

This works for me:

in /etc/avahi/avahi-daemon.conf [server] section:

use-ipv6=yes

Also change nsswitch.conf:

$ diff -u nsswitch.conf /etc/nsswitch.conf
--- nsswitch.conf 2009-04-16 11:30:17.132488848 +1000

It would make sense for these changes to be the default. Avahi works well on IPV6 and IPV6 is perfect for zero configuration link local devices.
