some weeks ago the trace to the anycasted 6to4 relay went (after norway)
across the atlantic.
Now no longer. Good.
If only it worked...

I think in the "traceroute6" you'll see the routing loop.

the whois (of the 'real' v6 IP) includes "OCCAID" in the result.
that rang a bell somewhere (dunno where).
http://www.occaid.net/  gives me.... same, nothing, likely v6

So my colleagues IPv4 workstation shows the same site.
And there's a news about ...."OCCAID and Consulintel"......
and Frank thinks of Jordi.....

HELP!!!!!

need more info than above ?

Guessing: a routing loop on v6 side behind a 6to4 relay (used from
TAIDE.NET - Norway)

Rgds,
Frank
