Bug Description
I have up recently upgraded from:
# lsb_release -rd
Description: Ubuntu 8.04.3 LTS
Release: 8.04
To:
# lsb_release -rd
Description: Ubuntu 10.04 LTS
Release: 10.04
And had turned off IPv6 with the following:
ifconfig ethX del addr/prefixlen
echo 'blacklist ipv6' | sudo tee -a '/etc/modprobe.
sudo sed -i -e 's/alias net-pf-10 ipv6/#&\nalias net-pf-10 off/' /etc/modprobe.
After the upgrade the system is showing that there is an IPv6 address assigned.
This is remove with ifconfig ethX del addr/prefixlen but:
There is no /etc/modprobe.
There is no documentation inregards to IPv6 at https:/
This is not a protocol that needs to be running on the system.
This should never have been reactivated by the upgrade.

A lot of things have changed since Hardy. I'm not familiar with Ubuntu server editions, but I believe I can provide an answer to your quandary. You could add a boot option that would disable IPv6, edit /etc/default/grub by adding ipv6.disable=1 to the GRUB_CMDLINE_ LINUX_DEFAULT line, then execute update-grub. Or, I'm not sure if network-manager is running on your server, but if it is then you could edit the eth0 connection and under the IPv6 Settings tab, choose Ignore in the Method field to obtain that address.
