I am trying to send ipv6 pings from a computer in a LAN. Unfortunately it does not work. It seems that I have an ipv6 address in the LAN, but somehow the ping -Ieth1 ipv6.google.com just prints a connect: Network is unreachable.Here is my routing table:    Kernel IPv6 routing table    Destination                    Next Hop                   Flag Met Ref Use If    fe80::/64                      ::                         U    256 0     0 eth1    ::/0                           ::                         !n   -1  1429877 lo    ::1/128                        ::                         Un   0   5     6 lo    fe80::9a90:96ff:fea4:e451/128  ::                         Un   0   2     5 lo    ff00::/8                       ::                         U    256 8 99924 eth1    ::/0                           ::                         !n   -1  1429877 loAnd this is the output of ifconfig:eth0  Link encap:Ethernet  HWaddr 98:90:96:a4:e5:49        UP BROADCAST MULTICAST  MTU:1500  Metric:1      RX packets:0 errors:0 dropped:0 overruns:0 frame:0      TX packets:0 errors:0 dropped:0 overruns:0 carrier:0      collisions:0 txqueuelen:1000      RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)      Memory:fb300000-fb37ffffeth1  Link encap:Ethernet  HWaddr 98:90:96:a4:e4:51        inet addr:172.20.33.53  Bcast:172.20.35.255  Mask:255.255.252.0      inet6 addr: fe80::9a90:96ff:fea4:e451/64 Scope:Link      UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1      RX packets:946567 errors:0 dropped:0 overruns:0 frame:0      TX packets:322832 errors:0 dropped:0 overruns:0 carrier:0      collisions:0 txqueuelen:1000      RX bytes:144448246 (144.4 MB)  TX bytes:68655794 (68.6 MB)      Interrupt:20 Memory:fb400000-fb420000lo    Link encap:Local Loopback        inet addr:127.0.0.1  Mask:255.0.0.0      inet6 addr: ::1/128 Scope:Host      UP LOOPBACK RUNNING  MTU:65536  Metric:1      RX packets:463549 errors:0 dropped:0 overruns:0 frame:0      TX packets:463549 errors:0 dropped:0 overruns:0 carrier:0      collisions:0 txqueuelen:1      RX bytes:113166471 (113.1 MB)  TX bytes:113166471 (113.1 MB)Any ideas on what might be the cause and what can I change?
i don't get ipv6. Why cannot I ping ipv6.google.com?
linux;ip;routing;ipv6;ping
You have only Link-Local, non routable ipv6 (fe80::/10).So You have no public routable IPv6.In this configuration You can make ipv6 connect only to Link-Local addresses in same L2 segment.
