IPv6 : traceroute6

ICMPv6, described in the IPv6 chapter of Computer Networking: Principles, Protocols and Practice is a companion protocol for IPv6 that is used for various functions including network debugging. traceroute6 is a popular debugging tool that allows to trace the path towards a destination.


Reorder UDP segments

traceroute6 sends UDP segments to probe a path. Can you reorder them in this packet trace ?
