Hi
Thank you for your help
I type the ifconfig -a
there is ipv6 address
inet6 fe80::20c:29ff:fe3c:92a1/64 scope link tentative
i also add one
inet6 2001:db8:cafe:1111::12/64 scope global tentative
but both are not pingable by ping6
Here are commands you suggested me to run
route -n -A inet6 Kernel IPv6 routing table Destination Next Hop Flags Metric Ref Use Iface 2001:db8:cafe:1111::/64 :: U 256 0 0 eth0 fe80::/64 :: U 256 0 0 eth0 ::1/128 :: U 0 2 1 lo ff00::/8 :: U 256 0 0 eth0
ip -6 route 2001:db8:cafe:1111::/64 dev eth0 metric 256 expires 21334307sec mtu 1500 advmss 1440 hoplimit 4294967295 fe80::/64 dev eth0 metric 256 expires 21330690sec mtu 1500 advmss 1440 hoplimit 4294967295
I can't ping ipv6.google.com but I should ping the eth0 ipv6 as it is host ip address. Right?
Thank you for your help.

Hi
I used the command "ip -6 addr add
2001:DB8:CAFE:1111::12/64 dev eth0"
to add ipv6 address and can see it in ifconfig
but can't ping it
Why?
Thank you

hi,
have you correctly set gateway? Send `ip -6 route` and `route -n -A inet6` to us. What about to ping ipv6.google.com from this pc? Where did you run ping command? Have you IPv6 enabled there? "From ::1" looks like something is misconfigured..
