Hi there!

Some days ago while talking to other 6to4-Users the question came up, on how to get reverse lookup on 6to4-addresses. A "dig -x 2002::" showed up the following result:

tcpdumb@beast:~$ dig -x 2002::

tcpdumb@beast:~$ 

##### snap

which would lead me to the thought that there is only one DNS where the SOA lies (not very redundant). An eMail asking the hostmaster whether it is possible or not to get the SOA for the own 6to4 address space (IPv4 registered at ripe, three Nameservers available) was left unanswered.

Question: Are there any international laws on my side?

Sorry guys but this is annoying!
