Re: what wrong about my ipv6 address

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



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.
