Can't ping IPv6 domains
Corwin Burgess
ipv6 module is loaded at boot but I can't ping6 any IPv6 domains. My D-Link DFE-530TX+ NIC
is connected to a cable modem. Not knowing what might be helpful I've included everything
I could find. I will provide any additional information that you need to provide suggestions.

IPv6 is not supported in the internet yet. If you want to send ipv6 packages
over the internet, you will have to tunnel them in an ipv4 tunnel. try "man
ifconfig" and search for the keyword "tunnel". Keep in mind, that the other side
of the connection will also have to support ipv6, which is not obvious.
ipv6 support in the internet is currently being discussed and will be introduced
step by step in the near future.

I finally found the information in the form that I could understand. All I had to do was
add NETWORKING_IPV6=yes to /etc/sysconfig/network and then run the script that I found at
the following link. If you compare my script with his you will see that I had to make a
slight change.
http://www.altocumulus.org/IPv6/
-- script --
#!/bin/bash
### Get the global IPv4 address for your host from the command line:
GLOB_IP4=$1
### Compute the 6TO4 tunnel IPv6 address:
GLOB_IP6TO4=$(printf "2002:%02x%02x:%02x%02x::1" $(echo $GLOB_IP4 | tr . ' '))
### Setup the tunnel
ip tunnel add tun6to4 mode sit remote any local $GLOB_IP4 ttl 64
ip link set dev tun6to4 up
ip addr add $GLOB_IP6TO4/16 dev tun6to4
ip route add 2000::/3 via ::192.88.99.1 dev tun6to4 metric 1
