What’s happening here? Is this a strange bug?

In case it is not clear, I am asking why eth0 has 13 ipv6 addresses.
This is 12.1. The system was installed about 1 week ago. When I ran that “ifconfig” it had been up for a little under 5 days since the last reboot. I have since rebooted, and the problem has not yet shown up.
The network is handled with “ifup”. It is set to use DHCP to get an ipv4 address, but no ipv6 address. I did not disable ipv6 support.
