Can't ping in ipv6

[idata]

network adapter:Intel(R) Gigabit CT2 Desktop Adapter & Intel(R) 82579LM Gigabit Network Connection

PC is from HP.OS is windows xp

all is good when IPV4.

below is the information when ping with ipv6 address:

C:\Documents and Settings\Administrator>ping 2001:db8:1234:5555::11 // ping

Pinging 2001:db8:1234:5555::11 with 32 bytes of data:

Destination host unreachable.

Destination host unreachable.Destination host unreachable.Destination host unreachable.

Ping statistics for 2001:db8:1234:5555::11:

Below are the packets captured by network packet capture tool WireShark.

Does it means that the packets already out of the TCP/IP protocol stack? and doesn't relative to OS?

of course,route table,are check again and again, my colleague's computer are ok in ipv6,his network adapter is

Realtek RTL8139/810x Family Fast Ethernet NIC

I have update the newest driver today, nothing changed.

Any more information needed,tell me.

Any one help me?

The IP stack is part of the OS. The network adapter does not do anything that would block the transmissions.

I am not an expert on IPv6, but I did some research to find out what the above information means. The clearest explanation I found is in the presentation at http://www.6net.org/events/training-2003/ipv6-basics.pdf http://www.6net.org/events/training-2003/ipv6-basics.pdf.

Slide 69 describes the neighbor discovery process that you are capturing. Before exchanging packets, for example the ping and the reply, a neighbor discovery process takes place. Your host sends the discovery packet to the Solicited-node multicast address of the host you are trying to ping. Your capture is not showing any reply. If no reply is received then the two hosts cannot exchange packets.

For troubleshooting, you might want to try capturing packets on the other host to see if the neighbor discovery packet is received and if a reply is being sent.

I hope this helps.

Hi Mark,thanks for your help.

I try to ping my colleague's pc,and try to capture packets to check whether neighbor solicited reach destination. The result is, the packets have not reached. The same when my colleague's pc ping my pc.but my colleague can ping others. so i think there is some thing wrong with my pc. OS config or adapter driver? not sure.

The adapter driver should be OK, but make sure you are using the latest software package. See my reply at /message/161334# 161334 http://communities.intel.com/message/161334# 161334 for a download link and other ideas.
