[Planetlab-devel] IPv6 support for MyPLC

[McGeer, Patrick C]

1. Yes, there are multiple (often, >= 20) vservers/machine.
2. I'll let Marc describe how IP config is done.  Or can we get enough
info just by logging into an arbitrary PL node and running ifconfig?

Rick, 

OK yes v6 makes that much better.

So are there multiple vservers per machine?

If you have a paper that explains how IP config is done I can go read
that too?  If answer is yes to the above next questions :--)

thx
