I'm puzzled; I have native v6 connectivity
to 6lab.cisco.com according to traceroute6
output, and yet the page says I'm connecting
to it via IPv4. :(
So, I did some poking; it seems 6lab.cisco.com
doesn't have working IPv6 for their stats system,
which makes me wonder how accurate the data
from it is likely to be:
mpetach at mintyHP:~> telnet -6 6lab.cisco.com 80
