I have new one...

While looking for NAT64-Software I was a victim of this (beautiful?) loop:

from 2003:63:241a:6200:beae:c5ff:feb5:2088

I get:

ping6 www.jool.mx
PING www.jool.mx(2001:1250:ffe0:1::8) 56 data bytes
>From 2806:0:0:100::1 icmp_seq=1 Time exceeded: Hop limit
>From 2806:0:0:100::1 icmp_seq=2 Time exceeded: Hop limit
>From 2806:0:0:100::1 icmp_seq=3 Time exceeded: Hop limit
>From 2806:0:0:100::1 icmp_seq=4 Time exceeded: Hop limit
^C

This time there are no difference between the ISPs I can use.

The traceroutes are attached.

Regards,
Thomas
