False negative for traceroute submission?
« on: April 23, 2016, 01:07:35 PM »

I got this error for a ipv6 traceroute submission:

It looks like you submitted an IPv4 traceroute instead of an IPv6 traceroute!

Here's the traceroute:
Code: [Select]
traceroute to 2001:6f8:200:1::5:33 (2001:6f8:200:1::5:33), 30 hops max, 80 byte packets

My guess is the ipv4 check matched for hop 14?

Here's the traceroute:
Code: [Select]
14  pc1-646.br11.gdbru.be.easynet.net (::ffff:87.86.71.163)  154.563 ms  154.812 ms  154.436 ms

Yes, and it turns out if you rewrite that line as:
Code: [Select]
14  pc1-646.br11.gdbru.be.easynet.net (::ffff:5756:47a3)  154.563 ms  154.812 ms  154.436 ms
then it works.  They check the form, not the content.
