Thanks, Louis.

Eric: Here's a Debian Howto:

   http://servernetworktech.com/2012/11/charter-ipv6/

But before you go there, in the material you sent previously, we see:

2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qlen 1000
    inet6 2602:100:6153:810d:1::1/32 scope global
       valid_lft forever preferred_lft forever
    inet6 fe80::250:bfff:feb5:368f/64 scope link
       valid_lft forever preferred_lft forever

and we see:

	auto eth0
	iface eth0 inet dhcp
	iface eth0 inet6 dhcp

Did you configure the IPv6 address yourself or did dhcpv6 configure it
for you?
