ipv6 problem

Hi all,

Anybody need a good laugh at somebody else's expense?

I screwed up a dns address and pointed it to China (1.something) instead 
of unrouteable (10.something).  A very *short* time later I was suddenly 
some sort of server for whomever in the world was looking for .CN, much 
of which was ipv6 advertisements, and to add insult to injury I found 
that I was trying resolve them.

Since this had become a major bandwidth consumer and no doubt confused a 
lot of routers around the world I'm pretty sure both the US spies and 
their CN counterparts got their eyes onto me.  Panicked laughter here :/

In my desperate attempts to track down the source of the problem I 
started to tear down anything ipv6.  Seems I've have managed to do so 
quite well.

I have 4 machines that won't speak ipv6.  modprobe ipv6 works on each of 
them, lsmod shows that they all have the ipv6 module installed.

Using iproute2:  "ip addr list"  shows only "inet" addresses but no 
"inet6" addresses.  Any attempt to "ip addr add dev ethX ipv6-addr" 
returns a "permission denied" regardless of user.

I don't remember any ON/OFF switch for ipv6.  (CRS)

Does anybody out there have any idea how to bring IPv6 back to life on 
these machines or perhaps any insight into just what the resident idiot 
may have done?

Thanks, Mike Wright (befuddled)
