Supermicro IPMI + IPv6

[ka9q]

With thanks to the people on this list, I just got 6rd going over Uverse down here in San Diego. I had noticed 6to4 wasn't working, went to investigate and discovered this discussion. Wonders never cease.

My traceroute path to the relay address 12.83.49.81 is as follows:

 1. uverse.local                                                           
 2. 99-71-136-2.lightspeed.sndgca.sbcglobal.net 
 3. 75.20.78.24
 4. 75.20.78.48
 5. 75.20.78.131
 6. 12.83.70.137
 7. 12.123.132.213
 8. 12.83.49.81

Delays were a remarkably flat 20-25 ms all the way up; the 20 ms is for the first IP entity on the other side of my VDSL2 link. I have never learned exactly where that is; is it in the cabinet down the street or somewhere in AT&T's vast cloud? THe 25 ms is for hop 8, so there's very little additional latency over what I normally experience from Uverse.

BTW, tracerouting from a static IPv4 address over Uverse has *never* worked; apparently the brain-dead 2WIRE box blocks the returning ICMP error reports. But it does work when you use the NAT in the 2WIRE; go figure.
