To start using IPv6 Problem Finder, simply import a Wireshark trace ..

IPv6 Problem Finder will allow you to decode the traces for IPv6 traffic. IPv6 will be the protocol for the coming years of the Internet. IPv6 is much more than just a bigger address.Just a few of the differences between IPv4 and IPv6 are:

  • ARP has been replaced by Neighbor Discovery
  • There are many more address types, and
  • Each interface can have multiple addresses

The first thing IPv6 Problem Finder will do is to detect IPv4 and IPv6 protocols in the trace.

Next, IPv6 Problem Finder will find out what type of IPv6 address is being used. Knowing the type of IPv6 address will tell you its capabilities and limitations. There are many new types of unicast and multicast IPv6 addresses being used.

Of course, IPv6 Problem Finder will geolocate the IPv6 addresses.

Next, IPv6 Problem Finder will do a detailed analysis of throughput (bytes in flight), duplicate segments, duplicate acks, hangs, resets, segmentation offload, and much more!

You may graph many IPv6 flow parameters for quick analysis including bytes, throughput, TCP errors, receive buffer size, and many more. This has helped us compare IPv6 and IPv4 throughput.

You can use IPv6 Problem Finder to:
  • Perform root cause analysis
  • Analyze DNSv6
  • Explain multicast, link-local, ULA address types
  • Decode ICMPv6
  • Match tunneled packets
  • Compare IPv4 / IPv6 capacity and throughput, and do it lots faster than you could do it manually!


IPv6 Problem Finder will not just help you diagnose problems with IPv6, it will help you learn and understand all the new protocols which are a part of IPv6. IPv6 Problem Finder is an invaluable part of your IPv6 lab tools.
