Thanks Daniel,
Yes, the 172.25.in-addr.arpa was a typo.
I will have a closer look at rfc2317.  I think this is the first time I heard
someone say 'bug' related to an rfc ;-)  
Also, is there not a draft specifying support for unicode character-set in DNS?
Microsoft started with the 'underscore', but i recall someone mentioning complete
unicode support..
Regards,
Johnny
