This is our old Q&A Site. Please post any new questions and answers at ask.wireshark.org.

I connected to IPv6 via Freenet6, logged into ipv6.google.com and captured the Wireshark trace.

In the trace it does not show any IPv4 address. Connection mode is IPv6-in-UDP-IPv4 Tunnel (NAT Traversal). My question is,

  1. shouldn't the tunnel be going through my IPv4 network?
  2. If it is not so how is the connection established with remote server?

If anyone knows please help me.

Thank You

Are you sure that there is no IPv4 layer in your packets? Keep in mind that looking at the packet list won't help since Wireshark will always show the "highest" IP address found in a packet, so if you transport IPv6 over IPv4 it will always show the IPv6 address. If you take a look at the decode of the packet you will see the real layers, usually: Ethernet -> IPv4 -> IPv6 -> TCP/UDP/ICMP... or (in your case) Ethernet -> IPv4 -> UDP -> IPv6 -> TCP/UDP/ICMP...
