NetScanTools Pro Traceroute can now do IPv6 traces. It can do native IPv6 (direct IPv6 connection) and tunneling traces such as through Teredo or 6to4. When you do a native IPv6 traceroute, you will potentially see every hop between you and the target. But with tunneling, it's different: you will see the tunneling server as the first hop even though it may be quite a few hops away. This is shown in the traceroute through a Teredo tunnel to ipv6.google.com shown below.
