Wireshark is a free and open source packet analyzer used for network troubleshooting and analysis. These activities will show you how to use Wireshark to capture and analyze IPv6 6to4 traffic. Note: These activities do not require an IPv6 Internet connection. 6to4 tunnels across IPv4.
To prepare for this activity:
Activity 1 - Capture IPv6 6to4 TrafficEdit
To capture IPv6 6to4 traffic:
Activity 2 - Analyze IPv6 6to4 TrafficEdit
To analyze IPv6 6to4 traffic:
- Observe the traffic captured in the top Wireshark packet list pane. Type ipv6.addr == 2001:4860:4860::8888 (lower case) in the Filter box and press Enter to select the generated traffic.
- Observe the packet details in the middle Wireshark packet details pane. Notice that it is an Ethernet II / Internet Protocol Version 4 / Internet Protocol Version 6 / Internet Control Message Protocol v6 frame. The IPv6 / ICMPv6 packets are encapsulated inside IPv4 packets and forwarded to the 6to4 relay at 220.127.116.11 for IPv6 forwarding.
- Close Wireshark to complete this activity. Quit without Saving to discard the captured traffic.
