I noticed the request comes from a link-local IPv6 address. Just to make 
sure: is the DNS server Radiator uses also aware of the link-local 
address too?  The address itself looks like something that has been 
manually configured, so some special settings are obviously involved.

Running something like

% host -a testing.private.net address.of.dns.server
or
% dig testing.private.net any @address.of.dns.server

might be something to check.
