At least Ronald will be able to reach his box now:

jeroen@purgatory:~$ traceroute6 kirk.rvdp.org

He uses the same uplink so the problem is gone for him.

On 2001:6e0::2 we currently see:
B>* 2001:610::/32 [20/0] via fe80::204:28ff:fe90:5c82, fxp1, 10:25:48
B>* 2001:610:240::/42 [20/0] via fe80::203:e3ff:fe58:63e1, fxp1,
3d15h11m

That /42 is RIPE-NCC-IPv6.
Also comparing this to the traceroute below, apparently our box received
it from edison at that moment.
I really like hop 6 though ;)

jeroen@purgatory:~$ whois 128.107.240.254
Cisco Systems, Inc. (NET-LEWIS-PRNET1)
   170 W. Tasman Dr.
   San Jose, CA 95134
   US

The path was: rvdp -> intouch -> intouch(1) -> edisontel -> cern ->
cisco -> lavanet -> hurricane(1) -> tanic-tw -> wide-jp -> odn-jp(2) ->
hurricane

(1) Some boxes use the last assigned address as it's source.
(2) hmmmm... We had some channel takeovers on IRCNet this weekend from
there, those where v4 socks proxys though.

Greets,
 Jeroen
